A rocket is launch from a tower. the height of the rocket y in feet is related to the time after launch X in seconds by the given function f(x)= -16x^2+130x+40

hope this is what you were asking for!

step-by-step explanation:

5 feet of chain cost $9

so the answer is 1.80

graphs that are inverses of each other are graphs where their slopes are reciprocals of each other for example say you have an original equation of y=2x. the inverse of that graph would be y=-1/2(x). also when you see a graph where the original and the inverse is graphed the angle around intersection is 90 degrees.
