Answer :

Answer:

D = {5, 6, 7 , 8}

R = {-3, -2, 0, 10}

Yes, this could be a function

Step-by-step explanation:

It's not too difficult to understand these types of questions but you have to understand the fundas first

Let's see what some of those terms mean

Domain
- is the range of input values a function takes. In this case we are not told it is a function but only a relation between x and y

x is input, y is output

so domain is all possible values of x from the table

D = {5, 6, 7, 8}

which is all the values of x in the table

This is notated in ascending order so still
D =  {5, 6, 7, 8}

Range
Range is set of all possible values for output - in this case y values are the output values so the range is

R = { 0, - 2 10, -3} which is all the value of y in the table

This is usually notated in ascending order which means

R = {-3, -2, 0, 10}

Is this a function?

A little more complex.

A relation is a function if for every output value there is only one input value

In other words if you pick a value for y, there should only be one x value

In this case, the relation is a function because for each y there is only one x value

Not to panic. Everything will go alright
