A diver is 19 meters below the surface of the water. Use an integer to represent how far the diver will need to travel to reach the surface.

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

After t seconds, a ball tossed in the air from the ground level reaches a height of h feet given by the equation h = 144t-16t^2. after how many seconds will the ball hit the ground before rebounding?

Do,h = (7, 9) (14, 18) the scale factor is
