Use the following function rule to find f(25). f(x) = 3sqrt x − 9 f(25) = _____

Identify Function and Input: Identify the function and the input value. We are given the function f(x) = 3sqrt(x) - 9 and we need to find the value of f(25).Substitute Input into Function: Substitute the input value into the function. f(25) = 3sqrt(25) - 9Calculate Square Root: Calculate the square root of the input value. sqrt(25) = 5Multiply by 3: Multiply the square root by 3. 3 * sqrt(25) = 3 * 5 = 15Subtract 9: Subtract 9 from the result of step 4. f(25) = 15 - 9Simplify Final Answer: Simplify the expression to find the final answer. f(25) = 6

Q. Use the following function rule to find

f(25)

\newline

f(x) = 3\sqrt{x} - 9

\newline

f(25) =

_____

Identify Function and Input: Identify the function and the input value. $\newline$ We are given the function $f(x) = 3\sqrt{x} - 9$ and we need to find the value of $f(25)$ .
Substitute Input into Function: Substitute the input value into the function. $\newline$ $f(25) = 3\sqrt{25} - 9$
Calculate Square Root: Calculate the square root of the input value. $\sqrt{25} = 5$
Multiply by $3$ : Multiply the square root by $3$ . $\newline$ $3 \times \sqrt{25} = 3 \times 5 = 15$
Subtract $9$ : Subtract $9$ from the result of step $4$ . $\newline$ $f(25) = 15 - 9$
Simplify Final Answer: Simplify the expression to find the final answer. $f(25) = 6$
