Given:
The set of pair and graphs.
To find:
The domain and range.
Solution:
We know that,
Domain is the set of x-values or input values.
Range is the set of y-values or output values.
(a)
The given set of ordered pairs is
{(-3,3),(5,5),(-3,2),(5,3)}
Here, the x-coordinates are -3, 5, -3, 5.
A set contains distinct values.
Therefore, the domain is {-3,5}.
(b)
The graph is given.
From the given graph the set of ordered pairs is
{(-2,1),(-1,0.5),(-1,3),(0,0),(0,2),(1,0.5),(1,3)(2,1)}
Here, the y-values are 1, 0.5, 3, 0, 2, 0.5, 3, 1.
Therefore, the range is {0, 0.5, 1, 2, 3}.
(c)
The graph is given.
From the given graph the set of ordered pairs is
{(-2,3),(-1,3),(0,1),(2,4)}
Here, the x-values are -2, -1,0, 2.
Therefore, the domain is {-2,-1,0,2}.
