3. Infer how doubling the initial velocity will affect the outcome of the maximum height. When the velocity of the projectile is 128 feet per second and is launched from an initial
height of 96 feet. Prove whether your inference coincides with your result.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
