Answer:
The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.

As ratio of parrot fish to clownfish is 4:3
which can be expressed as 4x:3x where x is a natural number.
as 4x = 20
so x = 5
so clownfish = 3x = 3*5 = 15
He saw 15 clownfish
Given:
The relation is:
![\{(1, 2), (3, 5), (-2, 2), (3,6)\}](https://tex.z-dn.net/?f=%5C%7B%281%2C%202%29%2C%20%283%2C%205%29%2C%20%28-2%2C%202%29%2C%20%283%2C6%29%5C%7D)
To find:
The pair of coordinates that clarify why this relation is not a function.
Solution:
A relation is called a function if there exist unique y-value for each x-value. In other words, if a relation has two outputs for a single input, then the relation is not a function.
The given relation is:
![\{(1, 2), (3, 5), (-2, 2), (3,6)\}](https://tex.z-dn.net/?f=%5C%7B%281%2C%202%29%2C%20%283%2C%205%29%2C%20%28-2%2C%202%29%2C%20%283%2C6%29%5C%7D)
This relation has two y-values 5 and 6 for a single x-value 3. Since the y-value is not unique all all values of x, therefore the relation is not a function.
Hence, the pairs of coordinates (3,5) and (3,6) clarify that the given relation is not a function.
