How to somve this question

Answer 1

Answer:

-1

Step-by-step explanation:

The given function, f(x), has three distinct parts.  We must find and choose the part whose domain includes x = 1.

This x = 1 is a member of the set 1 ≤ x < 2.  Therefore, we choose the 2nd part of this function:  evaluate -x^2 at x = 1.  This comes out to -1^2, or -1.  that's the second answer choice.
