Question

Which graph could represent a car that begins by increasing its speed, then travels at a constant speed, and then decreases its speed, as time increases?

Answer 1

What is the graph. But I know that if you want to find the constant Divide Y by X. If you want to find which graph is proportional then you have to find that graph that has a straight line that goes through the zero or else is not proportional

Answer 2

I don't know what the graphs are but it will be the one with a curvy line that curves up then a straight line then a curvy line going down.

Hope this helps :)
