football is kicked into the air, and its height (h) in feet after t seconds is given by . h(t)=-16t^2+42t a) What was the height of the football when it was kicked? b) How many seconds does it take for the football to reach its maximum height (to 3 decimal places, if needed)? c) What is the maximum height (to 3 decimal places, if needed)?
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.
