Use the following function rule to find f(5). f(x) = –3 − |x| f(5) = _____

Identify value for substitution: Step 1: Identify the value to substitute into the function. We need to find f(5), so we substitute x = 5 into the function. f(5) = –3 − |5| Calculate absolute value: Step 2: Calculate the absolute value of 5. |5| = 5, since 5 is a positive number. Now substitute back into the function: f(5) = –3 − 5 Perform subtraction: Step 3: Perform the subtraction to find f(5). f(5) = –3 − 5 = –8 This is the value of the function at x = 5.

Q. Use the following function rule to find

f(5)

\newline

f(x) = -3 - |x|

\newline

f(5) =

_____

Identify value for substitution: Step $1$ : Identify the value to substitute into the function. $\newline$ We need to find $f(5)$ , so we substitute $x = 5$ into the function. $\newline$ $f(5) = -3 - |5|$
Calculate absolute value: Step $2$ : Calculate the absolute value of $5$ . $\newline$ $|5| = 5$ , since $5$ is a positive number. $\newline$ Now substitute back into the function: $f(5) = -3 - 5$
Perform subtraction: Step $3$ : Perform the subtraction to find $f(5)$ . $f(5) = -3 - 5 = -8$ This is the value of the function at $x = 5$ .
