What are differences between speed and velocity, velocity and speed and acceleration?

Prove that f(x) the inverse function of g(x) where f(x)= - 3x–6 and g(x)= - x/3–2

Given that y=x^3 +2x^2, find dy/dx . Hence find the x-coordinates of the two points on the curve where the gradient is 4.

A ball is thrown in the air. The height of the ball at time t is given by: h=5+4t-2t^2. What is its maximum height? At what time does the ball reach this height?
