Q. Determine the value of

y

, if

x

is

-2

.

\newline

y=x^{2}-9

\newline

Answer:

Given Function and Value: We are given the function $y = x^2 - 9$ and asked to find the value of $y$ when $x$ is $-2$ . To find $y$ , we substitute $x$ with $-2$ in the equation and perform the calculation. $y = (-2)^2 - 9$
Calculate Square: Calculate the square of $-2$ . $(-2)^2 = 4$
Subtract $9$ : Subtract $9$ from the result of the square of $-2$ . $\newline$ $y = 4 - 9$
Find Value of y: Perform the subtraction to find the value of $y$ . $y = -5$
