HELP I DONT UNDERSTAND PLSS HELP :(

D

Step-by-step explanation:

The range of a graph is the span of y-values it covers.

From the graph, we can see that the span of y-values covered goes from y=-3 all the way to y=3.

However, note that at y=-3, while it is a closed circle, it is an open circle at y=3.

This means that we do not include y=3 in our range, but we do include y=-3 in our range.

So, our range is all values between -3 and 3 including -3.

In set notation, this is (and remember since this is the range, to use y):

So, our answer is D.

And we're done!

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
