Question

If there is a graph with a line going through (-1, -1), (0, 0), (1, 1), (2, 2) What is the domain and range?

Answer 1

Answer:

Step-by-step explanation:

Let Domainwill X and range(co domain)Y.

(X,Y),

domain(-1,0,1,2)

codomain(-1,0,1,2)

Answer 2

The graph is of identity function

$|x| = |y| \\ identity \: function \\ domain = r \: \times r \\ range = z + \: \times \: z + \\ z + = all \: + ve \: integer$
