Accepted Answer

$$f(x) = x^3$

Question 6

A medical researcher models the spread of a virus using $$f(x) = 2$$^{x-5}$$ + 10. $$What does the $$-5$$ inside the exponent represent?

Accepted Answer

A horizontal shift 5 units to the right.

Question 7

Which transformation will change the graph of $$f(x) = \sqrt{x} to$$ $$g(x) = -\sqrt{x+4} + 3$$?

Accepted Answer

Shift left 4, reflect over the x-axis, and shift up 3.

Question 8

Which of the following best describes the range of the absolute value function $$f(x) = |x|$$?

Accepted Answer

Accepted Answer

Shift right 1, reflect over the y-axis, vertically stretch by 2, shift down 4.

Question 11

Which of the following statements is true about the function $$f(x) = x^2$?

Accepted Answer

It is an even function because $$f(-x) = f(x).$$

Question 12

If $$f(x) = x^3$, what is the effect of the transformation g(x) = -f(x+2$$)$$?
