distance time graph The domain is 0$\leq$t$\leq$8.8 The range is 0$\leq$d$\leq$264 Speed time graph The domain is 0$\leq$t The range is s=30

#### Work Step by Step

distance time graph The domain is 0$\leq$t$\leq$8.8 The range is 0$\leq$d$\leq$264 The range and domain is this because the maximum distance the bike can go as far as 264 ft timed which is why at t=8.8 secs, the bike travels 264 ft. Speed time graph The domain is 0$\leq$t The range is s=30 The domain is any nonnegative number because for the speed time graph, time has no effect on the speed of the biker. However it is non negative because time can't be negative. The range is 30 because it is a horizontal line graph as the slope remains unchanged.
