Use the following function to find f(-2)? f(x)=x(squared)-3

This is how I am solving the problem:

f(x)=x(squared) -3

f(-2)=(-2)squared -3

f(-2)=4-3

f(-2)=1

The correct answer is 2 and I don;t know why.

You should have enough faith and trust in your own math ability to say "the book is wrong" on this one.
