A function is graphed on the coordinate grid. Possible inputs for the quadratic when the output is 3 are:

Jimmy is on the diving team at his school. The quadratic function graphed on the coordinate plane below represents one of Jimmy's dives, where x represents the horizontal distance, in feet, that he is from the diving board and y represents his height, in feet, above the water level. What does the x-intercept mean in terms of the context?

• Jimmy's height at the beginning of his dive.

• Jimmy's maximum height during his dive.

• Jimmy's distance from the diving board when he hit the water.

• How long it took Jimmy to reach the water.

While playing golf, John hit a golf ball from ground level. The time that the golf ball is in motion, x, is measured in seconds, and the height of the golf ball, y, is measured in feet.

Which statement(s) are true?

• The golf ball was hit from a height of 0 feet.

• The golf ball was hit from a height of 100 feet.

• The golf ball began to descend after 5 seconds.

• The golf ball began to descend after 2.5 seconds.
