graphing form for a parabola
Graphing Form for a Parabola

y = a(x – h)2 + k

( h, k ):The Vertex

The value of a

same

opposite

different forms for a quadratic
Different Forms For a Quadratic

Same “a”

Parent Graph: y = x2

Factored Form: y = __( __x ± __ )( __x ± __)

Standard form: y = ax2 + bx + c

Graphing Form: y = a(x – h)2 + k

standard form to graphing form factoring
Standard Form to Graphing Form: Factoring

Use an algebraic method to write in graphing form.

3. Average the x-intercepts for h

2

1. Find the value of a:

2. Find the x-intercepts

4. Substitute h into the rule for k

5. Substitute a, h, k into the graphing form

WARNING:

This method does not work if there are no x-intercepts
