Heather dropped a water balloon over the side of her school building from a height of 80 feet. The approximate height of the balloon at any point during its fall can be represented by the following quadratic equation:

h = -16t² + 80

About how long did it take for the balloon to reach a height of 30 feet?

• 1.77 seconds

• 2.24 seconds

• 2.45 seconds

• 2.83 seconds

The table of value represents a quadratic function. Which of the following functions yields the same minimum or maximum value as the table?

• f(x) = -x² + 4

• f(x) = x²+4x+4

• f(x) = 3x² - 5

• f(x) = -x² + 8

Determine the domain and range of the function

• Domain: All real numbers, Range: All real numbers

• Domain: x ≥ -4, Range: All real numbers

• Domain: All real numbers, Range: y ≥ -4

• Domain: -1 ≤ x ≤ 5, Range: y ≥ -4
