Use the piecewise defined function to answer the questions below. 40 x52 h (x) = X+3 B| X - 51 x > 2 (a) Find the average rate of change of h(x) from x = -2 to x = 4. 40 - B 6 O 6 40 - B O B - 40 2 B - 40 6 O 6 B - 40 (b) Find the value of B so that h(x) is continuous on the interval [1, 6] O There is no value of B. O B = 40/3 O B = 8/3 O B = 20/3 O B = 8 O B = 3/8
