B.{(8,-4), (-4, 8), (-4, -8), (-8,4)}
C.{(9, -1), (-1, 9), (9, 2), (2, -1)}
D.{(5, -7), (4, 6), (-3, 8), (5,9)}
A function means that each x can only have one y-value
B, C, and D are NOT functions because they have x-values that have multiple y-values.
For example
B. has two values for -4:
(-4, 8) and (-4, -8)
C. has two values for 9:
(9, -1) and (9, 2)
D. has two values for 5:
(5, -7) and (5, 9)
This makes A. the only function
Hope this helped!

Step-by-step explanation:
Area of a circle =
You can find the value of r by simply reversing the equation.
First, divide 113 by .
Next, root the value, and finally, round your final answer.
By the definition of inverse function,the point (a,b) lies on the graph So, (b,a) must be lies on the graph of .
Given:
Point (a,b) lies on the graph y= f(x).
Find:
The graph of must contain that point.
As per the definition of inverse function, if two one-to-one functions f(x) and g(x). If (f∘g)(x)=x and (g∘f)(x)=x. Then, we say that f(x) and g(x) are inverses of each other.
Then, its inverse is defined as
Therefore, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.
Thus, the point (a,b) lies on the graph So, (b,a) must be lies on the graph of .

Given:
Point (a,b) lies on the graph .
To find:
The point which is must be lies on the graph of .
Solution:
According to the definition of an inverse function, if a function is defined as
then, its inverse is defined as
It means, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.
We have a point (a,b) lies on the graph . So, (b,a) must be lies on the graph of .
Therefore, the correct option is (1).
