Given f(x) = -2(x + 5), find f(3)

f(3) = -16

Step-by-step explanation:

f(x) = -2(x + 5)

Let x=3

f(3) = -2(3+5)

Add the terms inside the parentheses

      =-2 (8)

      = -16

(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
