<h3>
Answer:</h3>
-1.25
<h3>
Step-by-step explanation:</h3>
In order to find the answer to your question, we're going to need to plug in a number to the variable x.
We know that x = -5
This means that whenever you see x, you would replace it with what it equals to. In this case, we would plug in -5 to x, since that's what it equals to.
Your equation would look like this:

Now, you would solve to get your answer.

Once you're done solving, you should get -1.25
This means that f(x) = -1.25
