Algebra 1: 10.2- Graphing Quadratics Learning Task/Big Idea: Students will learn how to graph quadratic equations by binding the vertex and whether the parabola opens up or down.
Notes: • Step 1: First decide if the graph opens UP or DOWN: • *If the term is ________________ the parabola opens _____________. • *If the term is _______________ them parabola opens ____________.
Ex.1: Determine if the parabola will open UP or DOWN: • A) B) • C) D)
Step 2: Second find the coordinates of the ___________. Then you can graph the quadratic using the vertex and which way the parabola opens.*Pick out a, b from the quadratic equation: *To find the x-value of the vertex we use the formula______________.*To find the y-value of the vertex you plug the x-value into the equation.
Ex. 2: Use step 1 and step 2 to graph the quadratic equation. (Decide which way the parabola should open and find the coordinates of the vertex, then graph) • A)
