Acannonball was was launched with an initial upward velocity of 55 ft./s from a tower 28 feet off the ground. the heart of the ball above the ground in feet can be modeled by an expression having the form -16t^2+bt+c

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
