Question

Let f(x)-3x+5, h(x)-4x-2 and g(x)=x^2. Write an expression for each function.

a. f+g
b. f-g

Answer 1

a. f+g = -3x+5 + x^2

b. f-g = -3x+5 - x^2

Explanation:

g(x) = x^2

I'll assume the other two equations were meant to be:

f(x) = -3x+5, and h(x) = -4x-2

a. f+g = -3x+5 + x^2

b. f-g = -3x+5 - x^2
