Question

What is the domain and range of ( (7.6, -0.2), (8.8, -0.2), (2.3, -4.6) )?

Answer 1

10

This is the answer

Answer 2

Given function = ( (7.6, -0.2), (8.8, -0.2), (2.3, -4.6) )

[ The reason why we call this a function and not a relation is, because In relation you only have domain and co-domain]

Domain is the set of values that are put into the function to obtain the range. They are the inputs. Usually, X coordinates, also called Abscissa gives the domain.

So from this, Domain = { 7.6, 8.8, 2.3}

Range is the set of values that are the results that are obtained after putting values of the domain into the function Usually, Y coordinates, also called Ordinate gives the range

Range = { - 0. 2, - 4.6}

( Here - 0.2 is not repeated twice since sets have distinct values and Range is also a set)

Finally,

We conclude that,

Domain = { 7.6, 8.8, 2.3}

Range = { - 0. 2, - 4.6}
