Deon throws a ball into the air. The height h of the ball, in meters, at time t seconds is modeled by the function h(t)= -5t^2+t+18. Will the ball reach a height of 21 meters?

Write the equations in logarithmic form 10^3=1,000

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
