The graph of f' (not f) is given below. x1 x2 x3 x4 x5 x6 At which of the marked values of x is A. f(x) greatest? x = B. f(x) least? x = C. f'(x) greatest? x = x2 D. f'(x) least? x = x4 E. f" (x) greatest? x = x1 F. f" (x) least? x = x3 用 (Note that this is a graph of f', not a graph of f.)

If xis large, which function grows faster, f(x)=2x or g(x)=x2?

During a nine-hour snowstorm, it snows at a rate of 1 inch per hour for the first 2 hours, at a rate of 2 inches per hour for the next 6 hours, and at a rate of 0.5 inch per hour for the final hour. Write and graph a piecewise-defined function that gives the depth of the snow during the snowstorm. How many inches of snow accumulated from the storm?

Find f(1) and f(2). f(x)=x+7
