Question

HELP!. Graph the relation. Find the domain and range.. . {(-1,1/2),(-1/2,-1),(3/2,0),(2,3/2)}

Answer 1

In the given set, {(-1,1/2),(-1/2,-1),(3/2,0),(2,3/2)}, the x-values are the values that will be a part of the domain i.e. domain will be {-1,-1/2, 3/2 ,2 } and the range will be {1/2, -1,0, 3/2}. Thus, the values of domain is the x-coordinate and range is the y-coordinate

Answer 2

we know that

A mapping diagram shows how the elements are paired. Its like a flow chart for a function, showing the input and output values.The input values are the elements of the domain and the output values are the elements of the range.

In this problem

Input Values (Domain) are

`[-1, -1/2, 3/2,2]`

Output Values (Range) are

`[1/2, -1,0,3/2]`

therefore

The answer is

Part a) The graph see the attached figure

Part b) Input Values (Domain) are
`[-1, -1/2, 3/2,2]`

Part c) Output Values (Range) are
`[1/2, -1,0,3/2]`
