1. a
2. 
Step-by-step explanation:
1. Since there is one value of y for every value of x in (−1,0),(−4,5),(3,2),(−3,5), this relation is a function.
2. To find the inverse, interchange the variables and solve for y.

Step-by-step explanation:
The formula for the area of a circle is π*r^2, r being the radius or the half line in the circle, and the formula for the circumference is π*r*2, or π*d, or the diameter which is the line that goes all the way through like number 5. The radius is half the diameter.
Answer:
Not a function because it does not pass the Vertical Line Test.
Answer:
It's A
Step-by-step explanation:
