Use the piecewise defined function to answer the questions below. 40 x +3 XS2 h(x ) = B | x - 51 x > 2 (a) Find the average rate of change of h(x) from x = -2 to x = 4. 0 40 - B 6 6 O 40 - B OB - 40 2 O B - 40 6 6 O 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
