I need help finding the difference quotient of f when f(x+h)-f(x)/h when h is not equal to 0. the problem is f(x)=x2(squared)+ 5x - 1
---------------------
f(x+h) = (x+h)^2 + 5(x+h) -1
f(x) = x^2 +5x -1
------------------------
f(x+h)-f(x) = 2hx+h^2+5h
------------------------
[f(x+h)-f(x)]/h = 2x+h+5
