A movie theater recorded its monthly revenue for the past 5 months. The table below shows the revenue as well as the price the movie theater charged for each ticket that month. Use vertex form to create a quadratic model that models the movie theater's revenue. Price ($) 10 11 12 13 14 Revenue ($) 3072 3792 4224 4368 4224 What is the vertex? ( Write the equation in vertex form: f(x) = a(x- )+ ) Now choose another point to find the value of a. Substitute that point into the vertex form of the function to find the value of a. a= Now write the vertex form of the function. f(x) = (x- )2+
