Find the inverse of the function f(x)=x-7

(x) = x + 7

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject, that is

y = x - 7 ( add 7 to both sides )

y + 7 = x

change y back into terms of x, then

(x) = x + 7

Step-by-step explanation:

Let the initial velocity of the ball is u.

At the maximum height the speed is zero.

Let the time is t.

Use first equation of motion.

v = u - gt

0 = u - g t

t = u/g

Let the maximum height is H.

Use third equation of motion
