X2 + y2 = 4
determine if the relation is a function

It is not a function.

Step-by-step explanation:

x^2 + y^2 = 4.

Let x = 1:

(1)^2 + y^2 = 4

y^2 = 4 - 1 = 3

So y = √3, -√3.

So we see that for one value of x we get 2 values of y.

So the relation is a one-to-many relation which is not a function.

Functions are either one-to-one or many to-one.

Since it is area, it is most defined as base times height, so the larger rectangle would be 9x14 which is 126 and the smaller rectangle is 6x8 which is 48, and since they are together in one shape, you can add both areas which would give you an answer of 174
