4. 10 Write Quadratic Functions and Models HEY GUYS THIS IS NIR, HUNTER AND CHRISTIAN TEACHING LESSON 4. 10 P-3 DUDA MATH
Goal and Vocab. O By the end of this lesson Hunter, Christain and I will teach you how to write a quadratic formula. • Vocab you need to know for the day… Best fitting quadratic model – The model given by performing quadratic regression on a calculator.
Important Formulas! • X & Y are found in the coordinates given in the problem (usually 2 nd set) • H & K are the 1 st set usually • As usual the X is the X coordinate and Y is the Y coordinate. • P & Q are the coordinates given on the Y axis • When you have 3 points given to you, you use this formula and the x’s are the x points, and same for the y. • A, B, and C you have to solve for.
Write a Quadratic Function in Vertex Form Y-Values 6 4 2 0 -5 -4 -3 -2 -1 0 -2 -4
Write a Quadratic Function in Vertex form O Your Points (-2, -3) (0, 5)
Write a Quadratic Function in Intercept form Q (2, 0) P (-3, 0) Y-Values 0 -4 -3 -2 -1 0 -1 -2 -3 -4 -5 1 2 3
Write a Quadratic Function in Intercept form O Your points P (-3, 0) Q (2, 0) X, Y (-2, 4)
CHECKPOINT O Write a quadratic function whose graph has the given Characteristics.
Write a Quadratic Function in Standard Form O Write a Quadratic function in standard form that goes through these points (-2, -6) (0, 6) (2, 2) Shown on board
