Answer: 40
Step-by-step explanation:
First find what 57 seconds in minutes is, 57 seconds equals 0.95 minutes
And then do distance/time=speed
38/0.95=40 m/min
At f(-3) the graph is equal to -9.
In order to find the point on the graph, move over to -3 on the x axis. Then move down to find the point where it hits the parabola. You'll see that the parabola hits at point (-3, -9).
