Question: Consider the function f(x) = 1/2x 2 . (a) Use a graphing utility to graph the function and estimate the values of f(0), f(1/2), f(1),

Consider the function f(x) = 1/2x2.

(a) Use a graphing utility to graph the function and estimate the values of f′(0), f′(1/2), f′(1), and f′(2).

(b) Use your results from part (a) to determine the values of f′(−1/2), f′(−1), and f′(−2).

(c) Sketch a possible graph of f′.

(d) Use the definition of derivative to find f′(x).
