Question

1. evan hits a golf ball with an initial velocity of 112 feet per second. the graph of function h represents the height of the ball in feet t seconds after evan hits it.

fill in each blank to complete each sentence.
the domain of h is ____. it represents the times from when evan hits the ball at __ seconds to when it lands at ____ seconds.

Explanation:

The domain of a function from a graph is the set of all valid input (x-axis, here $t$) values. The graph starts at $t=0$ (when the ball is hit) and ends at $t=7$ (when the ball lands, height = 0). This interval includes all times between 0 and 7 seconds.

Answer:

The domain of $h$ is $\boldsymbol{0 \leq t \leq 7}$ (or in interval notation $[0, 7]$). It represents the times from when Evan hits the ball at $\boldsymbol{0}$ seconds to when it lands at $\boldsymbol{7}$ seconds.
