Question 9

Which function is graphed on the right?

Revolt · Accepted Answer

B: y = 2x–3 + 2

Question 10

How can you use transformations to graph this function? Explain your steps.

Revolt · Accepted Answer

To graph the function y = 3 * 7^(-x) + 2, start with the parent function y = 7^x. First, reflect the graph across the y-axis to account for the negative exponent, which gives y = 7^(-x). Next, apply a vertical stretch by a factor of 3 to obtain y = 3 * 7^(-x). Finally, shift the graph vertically up 2 units to reach the final function y = 3 * 7^(-x) + 2.
