Question

PLEASE HELP ME I NEED HELP WITH THE BLUE LINE I GOT THE OTHER 2

Answer 1

f(x/4)

Explanation:

The red and orange lines are when f(x) is stretched vertically.

The blue line is when f(x) is stretched horizontally.

Comparing the blue line to f(x), we see that it is 4 times wider. Therefore, the blue line is f(x/4).
