Test 2 Section 4 number 26 please!

There’s my rendering of the figure. Let’s label the points we have.

The question asks you to identify whether a few different values of *f*(*x*) are equal to 1. There are a bunch of times when the *f*(*x*) graph equals 1, shown in green below:

Remember this trick about converting function notation to points on a graph. If *f*(*a*) = *b*, then (*a*, *b*) is on the graph of the function *f*. So when the question asks you whether , , and equal 1, you should check to see that , , and are all on the graph. Those points are in blue below.

All three points the question asks about are on the graph, so the answer is **D) I, II, and III**.
