For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.
Axls of symmetry: x = -0.5; Vertex: (-0.5, -0.5); f(x) = -2x2 - 2x - 1
Axis of symmetry: x = 0.5; Vertex: (0.5, -0.5); f(x) = 2x2 - 2x - 1
Axis of symmetry: * = -0.5; Vertex: (-0.5, 0.5); M(x) = -2x2 + 2x - 1
Axis of symmetry: x = -0.5; Vertex: (-0.5, -0.5); M(x) = -2x2 + 2x - 1

Can someone check if i did this correct. it’s number 4 if you’re wondering.

The probability that a student graduating from suburban state university has student loans to pay off after graduation is .60. if two students are randomly selected from this university, what is the probability that neither of them has student loans to pay off after graduation?

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
