    min
    cannot be determined
  • Question 2
    60 seconds
    Q. True or false:
    The solution, root, x-intercept, and zero of a problem are all the same thing
    answer choices
    True
    False, because the solution and root are the same but the x-intercept and zero are different
    False, because the x-intercept and root are the same but the zero and solution are different
    False, they are all different

    answer choices
    3
    2
    0
    1
  • Question 8
    60 seconds
    Q. Does the following quadratic equation have a maximum or minimum value? How can you tell?
    y=x
    ²+2x-3
    answer choices
    Minimum value, because the a value is positive
    Maximum value, because the b value is positive
    Maximum value, because the a value is positive
    Minimum value, because the c value is negative
  • Question 9
    60 seconds
    Q. What is the domain of f(x)=x²-4 ?
    answer choices
    −∞ ≤ x ≤ +∞
     x ≥ -4
    −∞ ≤ y ≤ +∞
     y ≥ -4
  • Question 10
    300 seconds
    Q. Solve the equation using the quadratic formula.
    answer choices
    A
    B
    C
    D
  • Question 11
    60 seconds
    Q. What is the arrow pointing at? How can you use this value?
    answer choices
    The arrow is pointing at the y-intercept. The x-value is the axis of symmetry and the y-value of this point is equivalent to the maximum/minimum 
    The arrow is pointing at the vertex. The x value of this point is equivalent to the maximum/minimum and the y-value is the axis of symmetry
    The arrow is pointing at the solution. The y value of this point is equivalent to the maximum and the x value is equivalent to the minimum
    The arrow is pointing at the vertex. The x-value is the axis of symmetry and the y-value is equivalent to the minimum/maximum
