**1. Homework Statement**

The first one says use the limit definition to find the derivative of the function.

F(x)= 1/(2x-4)

the second one is use the limit definition to find the derivative at the indicated point..

f(x)= -x^3 + 4x^2, at (-1,5)

the last one is use the limit process to find the slope of the graph of the function at the specified point.

f(x)= sqrt of (x + 10), at (-1,3)

**2. Homework Equations**

i know that this equation is used to help find it..

F(x + P)- f(x)/ P

p=the change in x..or delta x

**3. The Attempt at a Solution**

i dont even know where to begin ...but any help at all is welcomed and thanked.
