Question 1
Which of the following is the standard form equation of a vertical parabola?
y = ax2 + bx + c
x = ay2 + by + c
y = a(x - h)2 + k
x = a(y - k)2 + h
Question 2
What is the vertex form equation of a parabola with a vertex at (h, k) and a horizontal axis of symmetry?
y = a(x - h)2 + k
x = a(y - k)2 + h
y = ax2 + bx + c
x = ay2 + by + c
Question 3
Which of the following is the focus-directrix form equation of a parabola?
y = ax2 + bx + c
x = ay2 + by + c
(x - h)2 / 4p = y - k
(y - k)2 / 4p = x - h
Question 4
What is the standard form equation of a parabola with a focus at (0, 2) and a directrix y = -2?
y = 2x2
y = x2 + 4
x2 = 8y
y = x2 - 4
Question 5
What are the coordinates of the vertex of the parabola represented by the equation y = x2 + 4x + 3?
(-2, 1)
(-2, -1)
(-4, -2)
(-4, 2)
