The graph of the piecewise function f(x) is shown.

what is the domain of f(x)?
{x | 1 < x < 5}

{x | 1 < x < 5}

{y | −4 < y < 1}

{y | −4 < y < 1}

First of all, it asks for domain, which is allowed x values.

So immediately we can rule out last 2 answer choices.

If you look at the graph, the allowed x values are from 1 to 5.

Note: closed circle means that number is included and open circle means that number is NOT included

Now we see that 1 has closed circle so 1 is included and there is an open circle at 5, so 5 is NOT included.

Correct domain is {x | .

ANSWER: Domain is {x |

the correct answer is 828.07
