  • Question 6
    180 seconds
    Q. What could be the equation for this graph?
    answer choices
    y = -2x+ 1x + 3
    y = (x - 2)(x + 1)(x + 3)
    y = (x + 2)(x - 1)(x - 3)
    y = -2x2 + 1x + 3
  • Question 7
    180 seconds
    Q. Which equation MOST LIKELY matches the graph?
    answer choices
    y = x- x3 + 3x2 + 2
    y = -x4 + x3 + 5x + 2
    y = x3 - 2x2 + 1x + 3
    y = -x3 - 2x2 + 1x + 3
  • Question 8
    180 seconds
    Q. Which standard form function matches the factored form:
    y = (x + 1)(x - 3)
    answer choices
    y = x2 + x - 3
    y = x - 2
    y = x2 - 2x - 2
    y = x2 - 2x - 3
  • Question 9
    300 seconds
    Q. Which standard form function matches the factored form: 
    y = (x + 1)(x - 1)(x + 4)
    answer choices
    y = x3 - x2 - 4x
    y = x3 + 4x2 - x - 4
    y = x3 - 4x2 + x + 4
    y = x3 + x2 - x - 4
