All that f(-1) is telling you to do is to evaluate the given function of x [that is, f(x)]
when x is equal to -1.
.
All you do is take the given function and substitute -1 for every x. Once you do that, you
just reduce the answer.
.
So start with
.
Then substitute -1 for every x to get:
.

.
Multiply out the 4 times -1 and the equation becomes:
.

.
Then combine the -4 and -3 and you have the answer of:
.
