What is the average rate of change from x = 0 to x = 5? -80 -40 -8 -2 what is the average rate of change from x = 10 to x = 15? -8 -4 -3 -2 the first question is -8. the second question is -2.
Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.
