Thread: f(x)

f(x)=4x+3
solve f(x+h)-f(x)/h

(x+h)-f(x)/h

I cannot solve this, since there is nothing to solve. What's it equal to? Do you mean simplify?

it says break it down to one number.
4x+3 is given

Find F idk im losted

Well,
(x+h)-f(x)/h is equal to

= [h(x+h) - (4x + 3)] / h

= [h^2 + hx - 4x + 3] / h

= [h^2 + (h-4)x + 3) / h

EDIT:// with the question edited, it is now clear.

Do you mean?





if so...

Spoiler:

I dont get where the 4 come from

The h's cancelled.
