Question

Find the domain and range of the relation. {(−7,−18),(−23,21),(4,13),(−17,22),(2,−10)}

Answer 1

Answer: Domain = all x values and Range = all y values

Explanation:

The domain of a function is all the allowed x values that make the function true. Luckily you were already given the domain. Its all the x values.

The range of a function is pretty much all the allowed y values of a function. Or, what y values the function can be equal to. So that's just all the y values

When listing the domain and range, you generally want to do it from least to greatest and you do not want to repeat any values

Answer 2

D:{ -23,-17,-7,2,4}

R:{-18,-10,13,21,22}

Explanation:

The domain is the input

D:{ -7,-23,4,-17,2}

We normally put them in numerical order

D:{ -23,-17,-7,2,4}

The range is the output

R:{-18,21,13,22,-10}

We normally put them in numerical order

R:{-18,-10,13,21,22}
