Question

Which rule should be applied to reflect f(x) = x^3 over the x axis?

A. Substitute -x for x and simplify f(-x)
B. Multiply f(x) by -1
C. Switch the variables x and y in the equation
D. Multiply f(y) by -1

Answer 1

B. Multiply f(x) by -1.

Explanation:

By multiplying f(x) by -1. That is:

`g(x) = - x^(3)`

Hence, the right choice is B.

Answer 2

B. Multiply f(x) by -1

Explanation:

When we want to reflect over the x axis f(x) becomes -f(x)

so x^3 becomes -x^3
