Graph the equation.
.Graph the equation. Tell whether the equation is a function.
The brown-headed cowbird does not raise its own offspring. It lays eggs in the nests of other bird species, which then hatch the eggs and raise the young. A scientist investigated whether the growth of a young cowbird is affected by the species of bird that raises it. The scientist’s results for two bird species are shown below.

Spacecraft in 1997, the Pathfinder spacecraft landed on Mars. It contained a robotic vehicle named Sojourner that could roam up to 500 meters from the lander. The distance d (in meters) that Sojourner could travel in t hours is given by. How long would it take Sojourner to reach its maximum distance from the lander?
1. Copy and complete the table using the given equation
0 | 5 | 10 | 15 | 20 | 25 | 30 | |
? | ? | ? | ? | ? | ? | ? |
2. Use your completed table to graph .
3. Find the point on the graph whose d-coordinate is 500, and estimate the t-coordinate of this point. How much time would it take Sojourner to reach its maximum distance from the lander?
