To find the missing value for the function \( f(x) = x^2 \), you need to evaluate the function at the given input (x-value) to get its corresponding output (y-value).
If you have an ordered pair \( (x, y) \) from the function, where \( x \) is the x-value, then you can calculate \( y \) using the function:
\[ y = f(x) = x^2 \]
Please provide the specific ordered pair that you are looking for, and I can help you determine the missing value!
