What is the starting height of a ball that follows the path y = -16x2 + 8x + 5 ?
8 ft
5 ft
Not enough information
4 ft
What is the maximum height of the ball?
How many seconds will it take the ball to hit the ground?
h(t) = -16t2 +128t
When will the object reach its maximum height?
Based on the table, which function can best be used to model this situation?
h(t) = 99t2 + 858
h(t) = -4.9t2 + 295t + 0.6
h(t) = -4.9t2 + 295t + 2
h(t) = 99t2 + 1,470.3
Given the set of data, estimate what the value of y will be when x = 14. Round your answer to the nearest tenth.

For the function above, is the discriminant positive, negative, or zero?
For the function below, is the discriminant positive, negative, or zero?
___________
y = x² + 4x + 4
Positive
Negative
Zero
Not Sure
What is the discriminant of -2x2 − x − 1 = 0
76
-7
9
none of these
If the discriminant is positive, then the solution will be
one real solution
two real solutions
no real solutions
one imaginary solution
Which of the following represents the first step in solving:
y = x2 + 3x - 5
y = x + 3
x2 - 3x + 5 = x - 3
x2 + 3x - 5 = x + 3
x2 + 3x - 5 + x + 3 = 0
x2 + 3x - 5 = 0
y = x2 + 3x - 5
y = x + 3
