A projectile is fired from the origin over horizontal ground. Its altitude y (in feet) is a function of its horizontal distance x (in feet) and is given by y = 64x - 2x^2
a) Find the inverse function where the function is increasing.
b) Use the inverse function to compute the horizontal distance when the altitude of the projectile is (1) 32 feet, (ii) 256 feet (iii) 512 feet.
