if

f(5)

Identify Function & Value: Identify the function and the value of $x$ for which we need to find $f(x)$ . The function given is $f(x) = x^2 + 50$ , and we need to find $f(5)$ .
Substitute $x = 5$ : Substitute $x = 5$ into the function to calculate $f(5)$ . $\newline$ $f(5) = (5)^2 + 50$
Calculate Square & Add: Calculate the square of $5$ and add $50$ to it. $f(5) = 25 + 50$
Perform Addition: Perform the addition to find the value of $f(5)$ . $f(5) = 75$
