1 Review Problems Integration 1. Find the instantaneous rate of change of the function at x = -2 _ 1

2 Review Problems Integration 2. One of these curves is the graph of a function f, another is the graph of f’, and the third is the graph of f”. Which is which? _ A is f B is f’ when C crosses the x-axis B has an extrema, so B is f’ C is f” cannot be f because it has a minimum where no other curve has a zero. Same for f’ 2 A B C

3 Review Problems Integration 3. One of these three curves represents the position of a particle moving in a straight line, another represents the particle’s velocity, and the third represents its acceleration. Which curve is which and why? Curve A is acceleration Curve B is velocity Curve C is the position Neither B nor C crosses t at the points where A has extrema, therefore, A is not acceleration, nor position, so A is s”(t) It crosses the t-axis at the point where B has an extrema and C doesn’t, so B is s’(t), therefore, C is the position function 3 A B C

The functions f and g are differentiable and defined for all real numbers. The function h is given by h(x) = f(g(x)). Using the values of f, g, f’ and g’ in the table, find h’(1)
