Question

Can someone help me with functions?

the last option is:

each interval of the piecewise function contains a graph of a linear function.

Answer 1

Yes, the graph is a function and it does pass the vertical line test because when you hold a ruler up to it, you can see that the graph only hits one point at a time.(im not so sure about this, im sorry :/ )

Yes, your range is 2, since that is your y-intercept.

And your other answer choices are incorrect.
