TOPIC # 7 – 2: Graphing Quadratic Functions on the Calculator

NOW let’s find these points on the parabola. 1. Press . 2nd. CALC. 4. Do the same to find the other y-values. NOW sketch a graph using the vertex and points that you have found. NOW YOU TRY IT! 2. Graph the quadratic function and find its vertex and the y-values for the given . x-values. Then sketch a graph. y = -3x² - x + 7 Vertex:_____ ................
