Transcript text: If a function f is evaluated at 4 , the value of the function is 9 . Write this situation using function notation.
What is the function notation?
Solution
Solution Steps
To express the given situation using function notation, we need to write it in the form \( f(x) = y \). Here, \( f \) is the function, \( x \) is the input, and \( y \) is the output. Given that the function \( f \) evaluated at 4 gives the value 9, we can write this as \( f(4) = 9 \).
Step 1: Define the Function
We are given that a function \( f \) evaluated at \( 4 \) yields \( 9 \). This can be expressed in function notation as:
\[
f(4) = 9
\]
Step 2: Evaluate the Function
To confirm the output of the function at the specified input, we evaluate \( f(4) \):
\[
f(4) = 9
\]
Final Answer
The function notation representing the situation is:
\[
\boxed{f(4) = 9}
\]
