Use the two points given to find b and c. Write the function h(t ) = −5t 2 + bt + c. After 3 seconds, its height is 50 meters and after 5 A ball is thrown from some unknown height. Graphing Quadratic Functions (TB 3.07, 3.08)ġ3. Solving Quadratic Equations (TB 2.10, 2.11, 3.02)įinding the Equation of a Quadratic Function (TB 3.03) Factoring Non-Monic Quadratics (TB 3.04) 1. Here are some extra practice problems if you need more work on a particular topic. What was the highest the ball got, and when did it reach that height? When does the ball land? € What does the 25 in the equation signify? Graph the situation using an appropriate domain.Įxtra Practice: If you can do all the problems above correctly, you are in good shape. Its height in meters as a function of time since it € was thrown (in seconds) is given by the equation y = −5t 2 + 34t + 25. A ball is thrown upward from a flat surface. Sketch a graph clearly Free labeling: €Multi-Width Graph Paper from The vertex The zeros The axis of symmetry The y-intercept A mirror/sister pointĦ. Calculate your points and think about your scaling before graphing anything. Here is a quadratic in intercept form: y = −4(x − 2.5)(x + 8.5). € Sketch a graph clearly labeling: The vertex The zeros The axis of symmetry The y-intercept A mirror pointĥ. Here is a quadratic in vertex form: y = 4(x − 2) 2 −100 Calculate your points and think about your scaling before graphing anything. Write an equation in intercept form (factored form) so that the yintercept is (0, 6).Ĥ. Write an equation of the parabola in vertex form. A parabola has a vertex at (3, -8) and passes through the point (5, 20). Describe how to find the vertex of a parabola from each of the following forms of the equation. You will need separate paper to have room to do the problems. A scientific calculator is acceptable and will be allowed on the test. Solve a Quadratic Equation Quadratic Term Trinomial Non-Monic Equation Greatest Common Factor y-Intercept Minimum of a ParabolaĬompleting the Square Coefficient Standard (Normal) Form Vertex Form Factored Form Mirror Point Line of SymmetryĪll of this can be done without a graphing calculator.
