A ball was thrown upward into the air. The height in feet of the ball, above the ground, t seconds after being thrown

can be determined by the expression -16t² + 40t + 3. What is the meaning of the 3 in the expression.

A.) the ball took three seconds to reach its maximum height

B.) the ball took three seconds to reach the ground

C.) the ball was thrown from a height of three feet

D.) the ball reached a maximum height of three feet

can be determined by the expression -16t² + 40t + 3. What is the meaning of the 3 in the expression.

A.) the ball took three seconds to reach its maximum height

B.) the ball took three seconds to reach the ground

C.) the ball was thrown from a height of three feet

D.) the ball reached a maximum height of three feet

Using the graphing calculator,

you can see the graph of f(x) = -16t² + 40t + 3 is:

you can see the graph of f(x) = -16t² + 40t + 3 is:

The height at a time of t = 0 seconds is 3. Therefore, C.) the ball was thrown from a height of three feet.Ask Algebra House |
