MULTIPLE CHOICE QUESTION

A parabola has a vertex at (1,6) and passes through (3,-18). Write the equation in vertex form.
Formula: f(x) = a(x - h)2 + k
f(x) = 3(x - 1)2 - 18
f(x) = -6(x - 1)2 + 6
f(x) = 6(x - 3)2 - 18
f(x) = -3(x + 1)2 - 6

A parabola has a vertex at (-1.5,12.5) and passes through (0,8). Solve for "a" and write the equation in vertex form.
Formula: f(x) = a(x - h)2 + k
y = -1.5(12.5 - 8)2
y = 2(x + 0)2 + 8
y = -2(x + 1.5)2 + 12.5
y = 8(x + 1.5)2 - 12.5
None of the above

A parabola has a vertex at (6, 5) and passes through (10, -11). Which equation represents this parabola in vertex form?
Formula: f(x) = a(x - h)2 + k
-11 = a(10 - 6)2 + 5
y = -(10 - h)2 + k
y = -(x - 6)2 + 5
y = (x - 6)2 + 5

Given: vertex (1, 18) and zeros -2 and 4 What is the equation of the quadratic function in factored form?
y = 2(x -2) (x + 4)
y = -2 (x + 2)(x - 4)
y = 1/2 (x+ 2) (x - 4)
y = -1/2 ( x + 2) ( x - 4)

What is the equation of the parabola?
y =(x - 1)(x-3)
y = -1/2(x - 1)(x + 3)
y = 2(x + 1)(x - 3)
y = - 1(x- 1)(x - 3)
