Question

Find each new function in simplest form g-fWhich of the four options is it?

Answer 1

We have the following function given:

f(x) = x^2 +4x- 5

g(x) = 7x^2 -6x

And we want to find g-f, so we can do the following:

g-f = 7x^2 -6x -(x^2 +4x-5)

And if we distribute the terms we have this:

g-f = (7x^2 -x^2) -(6x +4x) -5

g-f = 6x^2 -10x +5

So then the best option for this case would be:
