Precalculus Example 2.4.4(4) - Suspected typo

MarkAU
In the solution to Example 2.4.4(4) on page 217, the first paragraph finishes with:

"in this region is [1,2)"

Shouldn't that be:

"in this region is [1,2]"?

Thanks again for reaching out.

Technically, we're looking only at the test interval [1,2) (ignoring the 2 at the moment.)
