The derivative of a function of f at x is given by

The derivative of a function of f at x is given by

f′(x)=limh→0f(x+h)−f(x)h

provided the limit exists.

 

Use the definition of the derivative to find the derivative of f(x)=7x2+3x+4.

 

Enter the fully simplified expression for f(x+h)−f(x). Do not factor. Make sure there is a space between variables.


f(x + h) - f(x) =

f'(x) =

This is merely substitute and simplify. What prevents you from doing that? ?
