STATION 1 Writing a Quadratic Model Standard Form *When you are given three points and told to write a quadratic model, you’ll have to use standard form unless you know that one of them is the vertex. Standard Form c bx ax y + + = 2 Directions : Use the three given points to write a quadratic model in standard form. ( Hint : you’ll want to create a system of three equations with a, b, & c as the variables. Once you solve, plug them back into the generic standard form) 3) (-1, 1); (0, 2); (1, -1) 2) (0, 0); (1, -4); (2, -4) 3) (0, -3); (3, -6); (5, -18)

STATION 2 Writing a Quadratic Model From A graph Vertex Form *If you have a graph, and you know what the vertex of the quadratic function is, the easiest thing to do is use vertex form. k h x a y + - = 2 ) ( Directions : Write an equation for the graph. ( Hint : fill in the values for the vertex, then use one of the other points to solve for a ) 1) 2) 3)
STATION 3 Graphing (using both vertex and standard forms) Standard Form c bx ax y + + = 2 Vertex Form k h x a y + - = 2 ) ( Axis of Symmetry a b x 2 - = h x = Vertex Find the y coordinate by plugging x back into the

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
