Creating the Graph
Watch the video to see how the key elements of the parabola help to construct the graph.
How to Graph a Parabola, Vertex, Axis of Symmetry and roots.
Equivalent Statements
We know writing equivalent statements is the key to mathematics. Each statement has a way of revealing a different piece of information. We will explore how the equivalent forms of a single equation can reveal key elements of the graph.
Let's take a look at how writing this function in factored form can help us find key elements of its graph.
1. Find the zeros of the function using the Zero Product Law.
2. Use that information to type in the correct x-intercepts. Then try to find the axis of symmetry and vertex to reveal the parabola.
