Which of the following is best described as a mathematical expression?
Whichever answer doesn't have an equal sign. (If it has an equal sign, it's an equation. If it doesn't, it's an expression.) √(a^2 + b^2)
You are reviewing a model your company has to calculate the cost to modify one of your software packages for individual usage. You need to update the model due to inflation and changes in the industry, and you have developed a transform that does exactly this. In particular, the updated cost is calculated by U(x) = 2.40C(x) − 400, where C(x) is the original cost. If a customer had originally been quoted a cost of $800 for modifying 5 software packages, what would the updated cost be?
$1520
A university parking lot designates spaces based on parking permit colors. The lot has 6 rows of 12 parking spaces each. The rows are labelled A-F and the spaces are numbered 1-12 in each row.
The different color permits are allowed to park as follows:
• Red permits may park in any space.
• Orange permits may park in any space in rows B-E.
• Green permits are allowed to park in row E spots 6-12 and (any spot) in row F.
• Blue permits may only park in row D.
Is the relationship that determines your potential parking space based on your permit color a function?
No.
What would be the independent variable in the generalized relationship that determines your potential parking space based on your permit color?
The color of your permit.
Which coordinates describe a point that is 2 units up and 8 units to the left of the origin?
(−8,2)
Which equation accurately reflects the following sequence of transformations? The
function g(x) is reflected over the y-axis, horizontally stretched by a factor of 3 and
shifted up by 4 units.

What is the parent function of g(x)= −x^4 + 10x^5 + 2x^3 + 11x^2 + 9?
f(x) = x^5
Consider the following graph of f(x) for the next 2 questions.
Based on the number of extrema, what is the smallest degree possible for the leading term of f?

Within which of the following segments is the function increasing and concave down?
Between b and c
Consider the polynomial p(x) = 33x^3 − 20x^2 + x + 26 for the next 2 questions.

What is the remainder when x4 −2x^3 −21x^2 +61x−45 is divided by x^2 +3x−10?
−x − 5
Consider the polynomial p(x) = x^3 − 4x^2 − 9x + 36. What is the sum of the zeros of p(x)?
