Question

What is the domain and range of the relation shown in the table?

x y
0 3
−1 4
4 2
−1 7


A. domain: {−1,0,4}{−1,0,4} , range: {y∣∣y∈ℝ}y∈ℝ

B. domain: {−1,0,4}{−1,0,4} , range: {2,3,4,7}{2,3,4,7}

C. domain: {x∣∣x∈ℝ}x∈ℝ , range: {−1,0,4}{−1,0,4}

D. domain: {2,3,4,7}{2,3,4,7} , range: {−1,0,4}

Answer 1

b is the correct answer

Answer 2

B.Domain={-1,0,1}

Range={2,3,4,7}

Explanation:

We are given that

x=0,-1,4,-1

y=3,4,2,7

Domain :It is defined as the set of values which are substituting in the function of x in place of x.

Range:It is defined as the set of values which are obtained corresponding to assigning values in any function .

Therefore,

Domain={-1,0,1}

Range={2,3,4,7}

Hence, option B is true.
