Which is the correct answer?
A)x=-5
B)x=0
C)x=5
D)x=y

C. x=5

Step-by-step explanation:

The axis of symmetry of the graph is equal to the x-coordinate of the vertex of the parabola.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
