Q. Determine the value of

y

, if

x

is

-9

.

\newline

y=|x|-4

\newline

Answer:

Substitute $x$ in function: Substitute the value of $x$ into the function. $\newline$ We are given the function $y = |x| - 4$ and the value of $x$ is $-9$ . We need to substitute $-9$ for $x$ in the function. $\newline$ $y = |-9| - 4$
Evaluate absolute value: Evaluate the absolute value of $x$ . The absolute value of $-9$ is $9$ because the absolute value of a number is the distance from zero on the number line, which is always positive or zero. $y = 9 - 4$
Perform subtraction: Perform the subtraction. $\newline$ Now we subtract $4$ from $9$ to find the value of $y$ . $\newline$ $y = 9 - 4$ $\newline$ $y = 5$
