Revolt · Accepted Answer

x = –4 and x = 6

Question 2

Which graph represents the function ?

Revolt · Accepted Answer

On a coordinate plane, a hyperbola and a cubic functions are shown. They hyperbola has curves in quadrants 1 and 3, and the cubic function goes through (0, 0).

Question 3

Megan borrowed $50,000 at 5% simple interest for 6 years. Joseph borrowed $60,000 at 4% simple interest for 8 years. The formula can be used to calculate the monthly payment, m, where P is the principle amount borrowed, r is the rate expressed as a decimal, and t is the amount of time for the loan, in years. Who will have a greater monthly payment, and by how much?

Revolt · Accepted Answer

Megan will pay approximately $78 dollars more per month

Question 4

Which statement describes the behavior of the graph of the function shown at the vertical asymptotes?

Revolt · Accepted Answer

As x approaches 7 from the right, y approaches –∞.

Question 5

How does the graph of compare to the graph of the parent function ?

Revolt · Accepted Answer

g(x) is shifted 4 units left and 6 units down from f(x).
