Question

Given: F(x) = x+2 and G(x)=3x+5

(F-G)(x)=

a. 4

b. -3x-3

c. -2x-3

Answer 1

Given: F(x) = x+2 and G(x)=3x+5; find (F-G)(x)=

You just substitute F(x) - G(x) into an equation and simplify

1. F(x) = x + 2
2. G(x) = 3x+5
3. F-G(x) = (x+2) - (3x+5) distribute the negative to both the 3x and the 5
4. x + 2 -3x - 5 gather like terms
5. -2x - 3 this should be the answer (C) Does the process make sense to you?

a. 4

b. -3x-3

c. -2x-3
