b. The function is compressed vertically by a factor of 13 .
c. The function is stretched horizontally by a factor of 3.
d. The function is compressed horizontally by a factor of 13 .

You can put this solution on YOUR website!
It doesn't matter what kind of function f(x) is -- linear, quadratic, exponential, logarithmic, trigonometric, or anything else; f(3x) is a horizontal compression of f(x) by a factor of 3.
I will assume that is what answer choice d is supposed to say; none of the answer choices you show is correct.
