Question

If f(x) = 3x2 - 4x + 5 and g(x) = 2x2 + 2,
find f(x) – g(x).

Answer 1

Answer: -x^2 - 4x + 3

Explanation:

when you distribute the negative sign and combine like terms you get : (f - g)(x) = x^2 - 4x +3

Answer 2

5-4x

Explanation:

Just use both equation given and substract as the questions asked you to.

f(x) = 3x2 - 4x + 5

g(x) = 2x2 + 2

(3x2 - 4x + 5) - (2x2+2)

6-4x+5-6

5-4x
