You can put this solution on YOUR website!
f%28-3%29=Why is+-%28-3%29-2
you are given
f%28x%29=+-x-2-> note you have minus sign in front of x, or your equation is f%28x%29=+-1%2Ahighlight%28x%29-2
if you need to find f%28-3%29, it means the value of x is -3, or simply x=-3
then you go to f%28x%29=+-1%2Ahighlight%28x%29-2, substitute x with -3
f%28x%29=+-1%2Ahighlight%28-3%29-2
f%28x%29=+3-2
f%28x%29=1
