If the line goes through (2,8) but the slope is undefined what is the equation?

x=2

Step-by-step explanation:

An undefined slope is a vertical line.

Vertical lines have the form

x=

Since we have the point(2,8) is goes through the point x=2

x=2

(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
