Question

Compute the derivative function f '(x) algebraically.
f(x) = mx + b

Answer 1

you want to do the delta x?

Answer 2

I am not sure what you mean by delta X

Answer 3

the limit,of the tangent line to the curve

Answer 4

f(x) = mx + b
f'(x) =lim [ m(x+h) + b -(mx+b)]/h
(h->0)
f'(x) =lim [ mx+mh) + b -(mx+b)]/h
(h->0)
f'(x) =lim m
(h->0)
f'(x) =m therefore m=slope

Answer 5

i did h instead of delta x

Answer 6

Thanks for the help. I was working in the right direction but got lost along the way.

Answer 7

ok yw..any more prob there? about derivatives?
