Homework Statement
use definition of derivitiave to find f'(c) EXACTLY
x3 - 4x2 + x + 8, c=1
Homework Equations
lim x->c f(x)-f(c) / x-c
The Attempt at a Solution
I got as far as (x3 - 4x2 +x + 2) - 6 / x-1
Plugging in 1 for x gives me divided by zero. The teacher's example, she factored an x-1 in the numerator and canceled it with the denominator, but she did an easy example that only had x2, and I have x3. How do I find an x-1 in the top?
:rofl::zzz:
