- 1. Multiple Choice
Is this a max or min?maxmincannot be determined - 2. Multiple ChoiceTrue or false:
The solution, root, x-intercept, and zero of a problem are all the same thingTrueFalse, because the solution and root are the same but the x-intercept and zero are differentFalse, because the x-intercept and root are the same but the zero and solution are differentFalse, they are all different - 3.

- 7. Multiple Choice.How many zeros does this parabola have?3201
- 8. Multiple ChoiceDoes the following quadratic equation have a maximum or minimum value? How can you tell?
y=x²+2x-3Minimum value, because the a value is positiveMaximum value, because the b value is positiveMaximum value, because the a value is positiveMinimum value, because the c value is negative - 9. Multiple ChoiceWhat is the domain of f(x)=x²-4 ?−∞ ≤ x ≤ +∞x ≥ -4−∞ ≤ y ≤ +∞y ≥ -4
- 10. Multiple ChoiceSolve the equation using the quadratic formula.ABCD
- 11. Multiple ChoiceWhat is the arrow pointing at? How can you use this value?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/minimumThe 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 symmetryThe 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 minimumThe arrow is pointing at the vertex. The x-value is the axis of symmetry and the y-value is equivalent to the minimum/maximum
