Answer: f(-3) = 11
Step-by-step explanation: Here we're given the function
f(x) = -2x + 5 and we're asked to find f(-3).
In other words, if we put an x into our function, we get a -2x + 5 out.
So what happens when we put a -3 into the function?
Well if we put a -3 into the function,
that's f(-3), we get a -2(-3) + 5 out.
Now all we have to do is simplify on the right side,
-2(-3) is 6, so we have 6 + 5 which is 11.
So f(-3) is 11.
