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

substitute -x for x and simplify f(-x)

Explanation:

Answer 2

B

Explanation:

given a function f(x) then - f(x) is equivalent to a reflection in the x-axis.

Hence multiplying f(x) by - 1 gives - f(x) a reflection in the x-axis
