difference quotient ...
I would start by expanding the expression for f(x+h)
Morning Forum any help with the following would be appreciated im having issues with it
Find the difference quotient for y = f(x) = 3x2 + 2, and evaluate it for
(a) h = 2 (b) h = 0.2 (c) h = 0.02)
(d) Describe what will happen as h gets smaller and smaller
Thanks - AC-
Do you know what the difference quotient is? It's a means of approximating the gradient of a point on a curve.
I'll leave you to do the research as to why, but the difference quotient is given by

Now evaluate this at your given values of h and tell me what happens as h gets closer and closer to 0.
