PROBLEM
What is if:
13
-13
17
-17
STEP 1
What is this asking?
We're given a piecewise function , which means it acts differently depending on the input , and we need to find what is!
Watch out!
Make sure to plug the value into the correct piece of the function!
It's easy to get mixed up!
STEP 2
1. Determine the relevant piece
2. Evaluate
STEP 3
Alright, so we have this funky function that changes its outfit depending on the value of .
When is greater than 4, dresses up as .
But when is less than or equal to 4, it prefers the disguise .
STEP 4
We're trying to find .
So our value is 7.
Since 7 is definitely greater than 4, we know which piece to use: the one!
STEP 5
Now, let's plug in our value, which is 7, into the correct piece of the function.
Remember, we decided that since is greater than 4, we're using .
STEP 6
So, we substitute into the expression:
STEP 7
First, we multiply:
STEP 8
Then, we add:
STEP 9
So, our final result is:
