Answer:

-5, 0, 1 , 5

Step-by-step explanation:

What you want to do is find all of the points on the graph:

(-5,-1), (-5,3),(0,3),(1,0),(5,2)

The domain would be -5,-5,0,1,5 because it is in the x-axis.

          Look at it as this (-5,-1) (-5,3) (0,3) (1, 0) (5,2)

   The numbers in bold  are the X-axis which is another word for domain

For example (-5, -1), -5 would be in the X-axis and -1 would be in the Y-axis, It goes "x,y" all the time.

Since there are two -5's on the domain, you just ignore one of the -5's.

Hope this helps!!

Jaylen is going to the store 2.5 miles away. He has only 15 minutes to get there before they close. At
Arturiano [62]

The average speed he must ride to get to the store before they close is a minimum of 10 mph

<h3>How to calculate average speed?</h3>

We are given;

Distance to store = 2.5 miles

Time to get to store = 15 minutes = 15/60 hours = 0.25 hours

Now, formula for average speed is;

Average speed = distance/time

Thus;

Average Speed = 2.5/0.25

Average Speed = 10 mph

Thus, we conclude that average speed he must ride to get to the store before they close is a minimum of 10 mph
