Let f(x) = 4x- - 2x + 9. Write out and simplify the following difference quotient. Your answer should be an non-fractional expression involving h. f(11 + h) - f(11) h Then, taking limit as h goes to 0, we get the derivative. f' (11) =Given rs} = 3 93:2, find f'fT] using the limit definition of the derivative. First, set up the limit. Your answer sheuLd he an expression incLuding h. Then compute the Limit: Let f() = V 27 - c. Compute f (2) using the limit definition f' (2) = Find an equation of the tangent line at r = 2 = /
