• y=x
• The quadratic is an equation containing one or more terms in which the variable is raised to the power of two.
Standard Formula

2

• y=ax+bx+c
• If the ax is a negative the parabola will open downward

2

Ta-da

2

• If the ax is less than 1 the parabola will be wider
• If the ax is greater than 1 the parabola will be narrower

2

Wide parabola

Narrow parabola

• The role for the a value helps choose whatever the parabola is opening down or up and narrower or wider
• The role for the b value help choose whatever it is shifted to the left or right
• The role for the c value show where the parabola points open down or up

The a value job

The b value job
