Question

State the domain and range of the following relation.

Answer 1

Answer:

D = {–3, –1, 1, 2}; R = {–3, 1, 2, 4}

Step-by-step explanation:

• We need to understand what is the domain of a function?

The domain is the set of all possible x-values which will make the function "work"

• We need to understand what is the range of a function?

the range of the function is the set of all values that f(x) = y takes.

In your question,

• all possible x-values : {–3, –1, 1, 2}
• all possible y-values : {–3, 1, 2, 4}  

So, the domain and range of the following relation is C

D = {–3, –1, 1, 2}; R = {–3, 1, 2, 4}

Answer 2

Answer:

Step-by-step explanation:

domain (ur x values) = -3,-1,1,2

range (ur y values) = -3,1,2,4

do not have to write them more then once

answer is C
