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)

Which of the following points is collinear with (-2,1) and (0,3)

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000
