Using calculus, it can be shown that if a ball is thrown upward with an initial velocity of 16 ft/s from the top of a building 700 ft high, then its height h above the ground t seconds later will be h = 700 + 16t − 16t2. During what time interval (in seconds) will the ball be at least 28 ft above the ground? (Enter your answer using interval notation
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
