Answer:
a relation and function ⇒ answer C
Step-by-step explanation:
* Lets revise the relation and the function
- The relation is between the x-values and y-values of ordered pairs.
- The set of all values of x is called the domain, and the set of all values
of y is called the range
- The function is a special type of relation where every x has a unique y
- Every function is a relation but not every relation is a function
* Lets solve the problem
∵ The graph is a parabola
∵ The parabola is a function because every x-coordinates of the
points on the parabola has only one y-coordinate
- Ex: some ordered pairs are (-5 , -5) , (-2 , 5) , (0 , 7) , (2 , 5) , (5 , -5)
∵ Every x-coordinate has only one y-coordinate
∴ The graph represents a function
∵ Every function is a relation
∴ The set of ordered pairs in the graph below can be described as
a relation and function
