Use the vertex form to write the equation of the parabola.
y = 3(x - 2)2 + 2
y = 3(x - 2)2 - 2
y = 3(x + 2)2 + 2
y = (x + 2)2 + 2

Use the vertex form to write the equation of the parabola.
y = -(x - 2)2 + 5
y = -3(x - 2)2 + 5
y = -3(x + 2)2 + 5
y = -3(x + 2)2 - 5

Suppose a parabola has vertex (-8, -7) and also passes through the point (-7,-4). Write the equation of the parabola in vertex form.
y = (x + 8)2 - 7
y = 3(x - 8)2 - 7
y = 3(x + 8)2 - 7
y = 3(x + 8)2 + 7

Suppose a parabola has vertex (1,-4) and also passes through the point (2,-1). Write the equation of the parabola in vertex form.
y = (x - 1)2 - 4
y = 3(x - 1)2 + 4
y = 3(x - 1)2 - 4
y = 3(x + 1)2 - 4

Suppose a parabola has an axis of symmetry at x=8, a maximum height of 1 and also passes through the point (9,-1). Write the equation of the parabola in vertex form.
y = -2(x - 8)2 + 1
y = -2(x + 8)2 + 1
y = (x - 8)2 + 1
y = 2(x - 8)2 - 1
