1. * (v) Fill in the blanks in the following table: f is concave up on (a, b) f is concave down on (a, b) 1]: 11 f' is on (a, h) f' is on (cab) 11 11 f" is on ((1,6) f" is on (a: b) 2. * (0) All three parts of this problem refer to the following graph: A (a) * m Assume that the graph is a graph of the function f. On approximately what interval(s) is f concave up? On approximately what interval(s) is f concave down? At what tvalues does f change c0ncavity'7 (b) * a Now assume that the graph is a graph of the function f'. This time, on what interval(s) is f concave up, and 011 what interval(s) is f concave down? At what Stevalues does f change concavity? (Hint: Use the second row of the table above.) (c) * 0 Now assume that the graph is a graph of the function f". On what inter val(s) is f concave up? On what interval(s) is f concave down? At What :tvalues does f change concavity? (Hint: Use the third row of the table above.)
