Function notation is an important idea that helps us understand functions in math.
When you see ( f(x) ), it means a function called ( f ) that uses an input ( x ).
Let’s break it down:
Function Name: The letter ( f ) tells us what the function is called.
Input Variable: The ( x ) is the number you put into the function. For example, if we have ( f(x) = 2x + 3 ), then ( x ) can be any number.
Output Value: The result, which is written as ( f(x) ), is found by putting ( x ) into the equation.
First, we replace ( x ) with ( 2 ) like this:
[ f(2) = 2(2) + 3 = 7. ]
Function notation is a simple way to show how different numbers relate to each other. It makes doing math and understanding results much easier!
