1.Which of the following statements is false?
a. The income effect of normal goods counters the substitution effect so the demand curve is upsloping.
b. The income effect and the substitution effect reinforce each other when there are price changes for a normal good.
c. The income effect represents the decrease in quantity demanded caused by the implicit change in income due to a fall in the price of an inferior good but not for a normal good.
d. The substitution effect represents the change in quantity demanded solely due to a change in the relative price of a good.

College Algebra, Week 3, Task 2
Reflect on the concept of polynomial and rational functions. What concepts (only the names) did you need to accommodate these concepts in your mind? What are the simplest polynomial and rational function you can imagine? In your day to day, is there any occurring fact that can be interpreted as polynomial and rational functions? What strategy are you using to get the graph of polynomial and rational functions?
Answer:
For polynomials, I needed to understand terms like coefficients, exponents, degree, leading term, and constant term. And for rational functions, I needed to grasp the concepts of numerator, denominator, domain, and vertical asymptotes. These concepts help me understand and work with polynomial and rational functions.

Please check the expression and answer the following questions.
With the help of zeros, asymptotes, domain, and range, try to plot the function without the Desmos graph-making tool, then plot the same with the Desmos graphing tool, and check if your plot is the same as the Desmos’s plot or not. If your graph was not the same as the Desmos graphing tool, write which point from your textbook (Abramson, J., 2021, Section 5.6) you missed while plotting the graph without the Desmos graphing tool.
Also, check the value of the function at x=3. What do you think about no values of the function at x=3?
Answer:
Let’s start by discussing the zeros and asymptotes of the rational function f(x).
Zeros of a function are the values of x for which the function equals zero. To find the zeros of f(x), we set the numerator of the function equal to zero (Abramson, 2021). So, we have:

1. Determine whether the lines given by the equations below are parallel, perpendicular, or neither. Also, find a rigorous algebraic solution for each problem.
To determine whether the given lines are parallel, perpendicular, or neither, we can compare their slopes. The slope-intercept form of a linear equation is y = mx + b, where m is the slope.
Let’s analyze each problem one by one:
a. {3y + 4x = 12, -6y = 8x + 1}
To find the slope of the first equation, we need to rearrange it into slope-intercept form:

Reflect on the concept of lines and quadratic functions. What concepts (only the names) did you need to accommodate the concept of lines and quadratic functions in your mind? What are the simplest line and quadratic function you can imagine? In your day to day, is there any occurring fact that can be interpreted as lines and quadratic functions? What strategy are you using to get the graph of lines and quadratic functions?
Answer:
In order to understand the concept of lines and quadratic functions, there are several key mathematical concepts that need to be accommodated in my mind. These concepts include slope, y-intercept, vertex, axis of symmetry, and the quadratic formula (Abramson, 2021).

Lines can be used to approximate a wide variety of functions; often a function can be described using many lines.
If a stock price goes from $10 to $12 from January 1st to January 31; from $12 to $9 from February 1st to February 28th; and from $9 to $15 from March 1st to March 31th. Is the price change of the stock $10 to $15 from January 1st to March 31st a straight line?
(more…)The Parthenon and the Pantheon: Reflections of Ancient Greek and Roman Cultures
The Parthenon in Athens and the Pantheon in Rome are two iconic architectural marvels that exemplify the distinctive styles and functions of their respective ancient Greek and Roman cultures. These structures not only showcase the exceptional craftsmanship and architectural prowess of their time but also reflect the values, beliefs, and societal norms prevalent in their societies. In this essay, we will explore how the style and function of each building serve as a typical example of its culture while highlighting the similarities and differences between ancient Greece and Rome.
The Parthenon; A Testament to Greek Culture:
The Parthenon, constructed between 447 and 438 BCE, stands as a testament to the Golden Age of Athens and the glory of ancient Greece (Britannica.com, 2023). This temple, dedicated to the goddess Athena, exhibits the refined and harmonious architectural style known as Classical Greek architecture. The Parthenon’s use of the Doric order, with its sturdy columns and restrained ornamentation, reflects the Greeks’ emphasis on balance, proportion, and simplicity.
The function of the Parthenon was primarily religious, serving as a place of worship and the treasury of the Delian League (Britannica.com, 2023). The friezes and metopes depicted mythological scenes, celebrating the achievements and virtues of the gods and heroes. Symbolically, the Parthenon represented the power, wealth, and cultural achievements of Athens, reinforcing the city-state’s identity as the cradle of democracy and the birthplace of philosophy, arts, and sciences.
