Homework Statement
If f(a) = 0 and f'(a) = 6 find lim h -> 0 (f(a+h)/2h).
Homework Equations
lim h ->0 (f(a+h)-f(a))/h
The Attempt at a Solution
I found the ratio between the two equations.
(f(a+h)-f(a))/h / (f(a+h)/2h)
I found this to be 2. Is this step possible or can you not take the ratio for first principles?
Then, I did:
lim h-> 0 (2(f(a+h)/2h) = 6
lim h-> 0 (f(a+h)/2h) = 3 (is this step also possible or is this incorrect?)
