9. A model airplane takes off at a constant rate of 15 feet per second. Its height, in feet, after t seconds is given by h = 15t. At the same time, a
ball is launched from ground level with an initial velocity of 45 feet per
second. The height of the ball, in feet, after t seconds is given by
h=-16t? + 45t. Will the airplane and ball collide? If so, find the time it
takes for the collision to occur.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
