Q. Determine the value of

y

, if

x

is

5

.

\newline

y=x^{2}-9

\newline

Answer:

Identify given function and x: Identify the given function and the value of $x$ for which we need to find $y$ . The given function is $y = x^2 - 9$ , and we need to find the value of $y$ when $x$ is $5$ .
Substitute $x$ into function: Substitute the value of $x$ into the function to calculate $y$ . $y = 5^2 - 9$
Calculate square of $5$ : Perform the calculation for the square of $5$ . $5^2 = 25$
Subtract $9$ from result: Subtract $9$ from the result of the square of $5$ to find $y$ . $\newline$ $y = 25 - 9$
Perform final subtraction: Perform the subtraction to get the final value of $y$ . $y = 16$
