For 1019, the first-quadrant part of a function graph is shown. a. Identify the type of function it could be. b. On what interval or intervals is the function increasing or decreasing, and which way is the graph concave? c. From your experience, what relationship in the real world could be modeled by a function with this shape of graph?

Chapter 13 In translational motion the more massive particle has the most rotational inertia Mass distribution with respect to the rotational axis also impacts rotational inertia; the farther away the mass is from the rotational axis the more rotational inertia will exist. Rotational inertia can be found by: n 2 I= ∑ m i i i=1 M is the mass of the particle r is the distance from the rotational axis The rotational inertia on a continuous object such as a bicycle wheel is:
