What is the effect on the graph of the function f(x) = x when f(x) is replaced with −f(x)?
a) shifts down 1 unit
b) shifts left 1 unit
c) vertical reflection over x-axis
d) horizontal reflection over y-axis

C

Step-by-step explanation:

Lets review some transformation rules. Let function be f(x). So:

Now, on to our question. We want to find what happens to parent function [f(x)] if we were to write it like  [-f(x)].

From the rules, we see that it is the second last one. This means it is a vertical reflection over the x-axis.

From the answer choices, the correct choice is C
