Equation problem

Question

If f(x)=x^2+9x-14 and g(x)=x^2-x+3.

Find (f-g)(x)

Answer 1

Hello Elisa,

By definition, (f-g)(x) = f(x) - g(x)

So in this case: (f-g)(x) = x^2+9x-14 - (x^2-x+3)

From there, you can distribute the negative sign to every term in the parentheses, then add/subtract like terms, and you will get the answer.

Cheers!
