Let
f(x) = 6×2 4x.
(a) Use the definition of derivative and the Procedure/Example box in this section to find the derivative.
f ‘(x) =
(b) Find the instantaneous rate of change of f(x) at x = 1.
(c) Find the slope of the tangent to the graph of y = f(x) at x = 1.
(d) Find the point on the graph of y = f(x) at x = 1.
(x, y) =
