1-7 Intro to Graphing Quadratics in Standard Form

Learning: I will graph quadratics from standard from

Habit: I will follow every step of this procedure

I know the parts of the graph of a quadratic

I can find and graph the x and y intercepts

I can find and graph the axis of symmetry

I can find and graph the vertex

I can sketch the graph of a quadratic using these key points

Substitute 0 for x and solve for y. This is the y intercept

Evaluate 

Graph the line of symmetry x=-b/2a 

Substitute your value for -b/2a for the x's in the equation and evaluate. This will give the y coordinate for the vertex. Graph the vertex.

Factor the quadratic, set to 0, and solve. Your solutions are the x intercepts aka the "zeros." Graph them.

Now connect your key points to sketch your parabola
