Question

If f(x) = 3x2 - 2x+4 and g(x) = 5x + 6x - 8, find (f-g)(x).

Answer 1

-2x^2-8x+12 if you meant the second function to be g(x)=5x^2+6x-8

If you didn't mean that please let me know in the comments so I can change my answer

Explanation:

f-g=

3x^2-2x+4

-(5x^2+6x-8)

--------------------

-2x^2-8x+12
