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

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

Answer:

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

Range={2,3,4,7}

Step-by-step 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.
