Question

Question 9: What is the domain and range of the function shown in the graph?( Make sure you choose one domain and one range.)

Answer 1

Domain:

In the graph, 'x' takes two groups of values:

`-5And:[tex]x>2`

So, the domain is:

`D=(-5,2)\cup(2,\infty)`

Range:

In the graph you can see that 'y' takes the value -4 for some values of 'x' (the ones between -1 and 2) and then, for the rest, it takes values greater than -2.

So, the range of this function is:

`R=\lbrack-4\rbrack\cup(-2,\infty)`
