  1. Find the standard equation of a parabola with vertex (−3, 2) and containing the point (1, 6).

    Answer: y= 0.25(x+3)2 +2

  2. Find the standard equation of a parabola with vertex (5,2) and containing the point (−1, 5).

    Answer: y=one-twelfth(x−5)2 +2

  3. Write a quadratic function that has x-intercepts (−5, 0) and (8,0), and passes through the point (5,5).

    Answer: y= −one-sixth(x+5)(x −8)

  4. Write a quadratic function that has x-intercepts (6,0) and (−4, 0) and passes through the point (−2, 16).

    Answer: y=−(x−6)(x+4)
