Morgan takes a 5 mile walk almost every day. For the first two miles, she walks at a rate of 4 feet per second. The rate
she walks for the next three miles is shown in the graph.
Compare the speeds for each part of her walk.

This should be a (2 and 3 only) because the graph never hits the x-axis so this rules 1 out. All of the other options have 1 in them so they are all incorrect. To check this we know the middle of the graph is x=2 making 3 true. 2 would be true because this is the point where the parabola hits the y axis.
