Question

The distance your car takes to stop depends on how fast you are going when you apply the brakes. You may recall that it takes more than twice the distance to stop your car if you double your speed.
1. How would I sketch a reasonable graph showing the stopping distance as a function of speed?
2. What is a resonable domain for this function?

Answer 1

well domain would be the speed of the car right? so i guess it would have to be positive

Answer 2

i am not sure exactly what the graph is supposed to look like but i imagine they want a line whose slope is somewhat larger than 1, so every time your speed doubles the stopping distance is greater than twice that number.

Answer 3

what's the rate of deceleration?

Answer 4

Wait! Is y dependent or independent?

Answer 5

i think it's dependent cause it depends on the rate of deceleration

Answer 6

but idk im not positive

Answer 7

this is like a physics problem lol

Answer 8

thanks anyways friend :)

Answer 9

sure anytime!
