How to Graph a Parabola, Vertex, Axis of Symmetry and roots.
Equivalent Statements
[size=150]We know [color=#0000ff][b]writing [/b][b]equivalent statements is the key[/b] [/color]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.[br][br]Let's take a look at how writing this [color=#ff0000][b]function in factored form[/b][/color] can help us find key elements of its graph.[br][math]f\left(x\right)=x^2+2x-3[/math][/size]
[size=150]1. Find the zeros of the function using the Zero Product Law.[br][math]f\left(x\right)=\left(x+3\right)\left(x-1\right)[/math][/size]
[size=150]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.[br][/size][br]
