SOLUTION: If f(x)=x^2+5, find f(a+h)-f(a). This one I'm having so much trouble with. I think it is 2ah+h2+10 but not sure. thanks for checking again.

Given that

then

and

hence f(a+h)-f(a) is

jon.

So, when x = a replace 'x' by 'a'
then,

Also, when x = (a+h) replace 'x' by (a+h)
then,
or

or
or

So your answer is incorrect.
