A rock is thrown from the side of a ledge. The height (in feet), x seconds after the toss is modeled by: h (3) = -4(x-2) square2 +293 How high was the platform at the time of the launch?

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
