Answer:
-13/-5
Step-by-step explanation:
To get G^-1 all we need to do is flip the points around Example for (5,3) make it (3,5)
Here are the points in inverse (3,5); (3,2); (4,6)
To tell if a group of point can be a function we need to 1st look at the x values. If all the x values are different, then it is a function (the x's are not all different)
If there are x values that are the same, they MUST have the same y value.
look at the points (3,5) and (3,2) those have the same x but they go to different y values so it is not a function.
You can think about it like this. Can you go to more than 1 place at the EXACT same time? Obvious answer is no. Can you have multiple people go to the same room? Sure that is possible. Same with functions. An x value can ONLY go to 1 y value, and many different x values can go to the same y value.

Answer:
75%
Step-by-step explanation:
75% families spent $260.00 or less on electricity in August because 3 quartiles are below the point marking the $260.00 mark. Each quartile represents 25% of the data entries and if 3 quartiles are below $260.00, then 25 * 3 = 75% of the families spent $260.00 or less on electricity in August.
