Evaluating functions using function notation is a fun skill that can lead to a lot of great math possibilities! Let’s break it down step by step:
What is Function Notation?: When you see something like , it means there's a function called "f" that uses "x" as an input. The output—what you get—is based on what the function does with that input!
How to Substitute Values: To evaluate a function, you just replace "x" with the number you want to use. For example, let’s say you have . If you want to find , you simply put 4 in for "x":
Understanding the Result: The answer you get, which is , tells you that when the input is 4, the output from the function is 11!
Keep practicing with different functions and numbers, and you'll become really good at evaluating functions in no time! Happy calculating!
