Suppose f(r) is a piecewise function defined as follows: if a < 1 2r + 2, ar + br, if l 2. 6 a) Suppose that a = 2 and b = -3. Graph f(a) for 0 3. Find the left and right hand limits of f(a) as a approaches 1 and as a approaches 2. b) Find a and b so that the graph of f(a) doesn't have any jumps (that is, f(a) is continuous everywhere). Graph the resulting function f(a) for 0 3.
