Q. Determine the value of

y

, if

x

is

4

.

\newline

y=x^{2}-11

\newline

Answer:

Identify function and x value: Identify the given function and the value of $x$ for which we need to find $y$ . The given function is $y = x^2 - 11$ , and we need to find the value of $y$ when $x$ is $4$ .
Substitute $x$ into function: Substitute the value of $x$ into the function to calculate $y$ . $y = 4^2 - 11$
Calculate square of x: Perform the calculation for the square of $4$ . $\newline$ $4^2 = 16$
Subtract $11$ : Subtract $11$ from the result of the square of $4$ to find $y$ . $\newline$ $y = 16 - 11$
Perform final subtraction: Perform the subtraction to get the final value of $y$ . $y = 5$
