Which of the following is the scaling factor a of the function f(x) = 3|x|? •-1 •-3 • 1 • 3

Last option: 3

Step-by-step explanation:

The following are some transformations for a function f(x):

1) If and , then this function is stretched vertically by a factor of "a".

2) If and , then this function is compressed vertically by a factor of "a".

Therefore, given the function , we can observe that the factor "a" is:

Then:

This means that  then this function is stretched vertically by a factor of 3.

Therefore, the scaling factor is 3.
