Answer:
f(-3) = -3
Step-by-step explanation:
Step 1: f(x) means "f of x" and f(-3) means "f of -3", so you have to replace all the "x" letters in the function with the value -3.

Step 2: Apply the exponents. <em>Make sure you remember to put in the -3 and not just 3.</em>

Step 3: Use BEDMAS rules to complete the calculation.


Therefore the answer is f(-3) = -3.
