The vertex form of a quadratic function is f(x) = a(x - h)2 + k. What is the vertex of each function? Match the function
rule with the coordinates of its vertex.
f(x) = 5(x - 6)2 + 9
(5.-9)
f(x) = 6(x + 9)2 - 5
(-9,-5)
f(x) = 9(x - 5)2 + 6
(-5.-6)
f(x) = 9(x + 5)2 - 6
(5,6)
f(x) = 6(x - 5)2 - 9
(6,9)

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

What is the inverse of the function f(x) = 2x + 1?

Mason and christian go to the movie theater and purchase refreshments for their friends. mason spends a total of $45.75 on 3 bags of popcorn and 6 drinks. christian spends a total of $71.50 on 6 bags of popcorn and 4 drinks. write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. using these equations, determine and state the price of a drink, to the nearest cent.
