Question

F(x) = 2x+1 and g(x) =x^2-7 find (f-g) (x)

Answer 1

-x^2 +2x +8

Explanation:

F(x) = 2x+1

g(x) =x^2-7

(f-g) (x) =2x+1 - ( x^2 -7)

Distribute the minus sign

= 2x+1 -x^2 +7

-x^2 +2x +8

Answer 2

(f - g)(x) = -x² + 2x + 8

Explanation:

Step 1: Plug in variables

2x + 1 - (x² - 7)

Step 2: Distribute the negative

2x + 1 - x² + 7

Step 3: Combine like terms

-x² + 2x + 8
