Can i get some pls;

make a mapping diagram for the relation.
{(-3, 1), (0, 6), (3, 2), (5, -1)}

Hi!
A mapping diagram is where the domain of a set of coordinate points is in the left box, and where the range is in the right box, (doesn't necessarily have to be a box), and all the numbers are interconnected based on the coordinate points.
The domain is each unique x coordinate of a coordinate point put together into a set and in numerical order, and the range is each unique y coordinate of a coordinate point put into a set in numerical orer.
The arrows are what connect a domain value to it's respective range value. For example, the domain value -3 would be connected to the range value 1 with an arrow.
So in this case, -3 would be connected to 1, 0 to 6, 3 to 2, and 5 to -1.
You're now just looking for an example where all of those are connected with arrows, and in numerical order. That would be the first choice in your first picture.

So .125 or 1/8 = 25 so 25 times 8 = 200 people called
