Question 11 • CREDIT RE-SEAT MNPS Integrated Math III IC S2 26-27

Which statements did you include in your answer?

Answer

Isolate sin(x) by adding 4 and taking the square root of both sides.

State that sin(x) = 2 or sin(x) = –2.

State that –2 and 2 are undefined values of the inverse sine function.

There are no solutions because –2 and 2 are not in the domain of the function.
