Parabolas
I can recognize that a parabola represents a nonlinear relationship.
I can write factored quadratic expressions in expanded form using the distributive property.
I can use a quadratic equation to find the y-intercept of the graph.
I can use a quadratic equation to find the x-intercepts on a graph. Note that x-intercepts may also be called zeros or roots.
I can use a quadratic equation to find the axis of symmetry on a graph.
I can use a quadratic equation to find the vertex and maximum/minimum on a graph.
