Standard Form, Vertex Form, and Intercept Form Quiz

How do you find the A.O.S. for vertex form?

'h' is the axis of symmetry

What is the significance of the 'a' term in standard form?

If 'a' is positive the parabola opens up, if 'a' is negative parabola opens down

How do you find the vertex for a vertex form equation?

The vertex is point (h,k)

How do you find the x-intercepts in an intercept form equation?

The x-intercepts are the coordinates (p,0) and (q,0)

How do you find the vertex for an intercept form equation?

Use equation p+q/2 and plug in the x value into the equation y=a(x-p)(x-q)

How do you find other points on the parabola?

Use five x coordinates(2 up and 2 down) and plug those into the equation.

How do you find the A.O.S. for standard form?

Use the equation -b/2a

How do you find the A.O.S. for Intercept Form?

Use the equation p+q/2

How do you find the vertex for a standard form equation?

Use the x coordinate for the axis of symmetry and plug it into the equation.

Vertex Form Equation

y= a(x-h)2 + k

Intercept Form Equation

y= a(x-p)(x-q)

Standard Form Equation

y= ax2 + bx + c
