The position function of an alien spaceship in a cartoon video game is represented by s(t) = t – 12t + 36 where t is measured in seconds, 0

Please find where the function increases and/or decreases.

An object is tossed vertically upward from ground level. Its height  s(t),  in feet, at time t seconds is given by the position function  s = −16t2 + 112t. In how many seconds does the object return to the point from which it was thrown?

Jerry is driving across the country at a constant speed.   Jerry enters Intersate 90 and and starts a clock as he passes mile marker 52.   After 5.4 hours, Jerry passes miles marker 484.   Represent the time elapsed in hours using the independent variable t.   Represent the mile marker passed at time t with the dependent variable x.   At what speed is Jerry driving? miles per hour   Write a formula to compute the mile marker x as a function of t.   x=   What mile marker is Jerry passing when 8.6 hours have elapsed?
