Q. Determine the value of

y

, if

x

is

-4

.

\newline

y=x^{2}-3

\newline

Answer:

Substitute $x$ into function: Substitute the value of $x$ into the function. $\newline$ We have the function $y = x^2 - 3$ and we need to find the value of $y$ when $x$ is $-4$ . $\newline$ Substitute $x = -4$ into the function. $\newline$ $y = (-4)^2 - 3$
Calculate square of $-4$ : Calculate the square of $-4$ . $(-4)^2 = 16$ Now, we have $y = 16 - 3$ .
Subtract $3$ from $16$ : Subtract $3$ from $16$ to find the value of $y$ . $\newline$ $y = 16 - 3$ $\newline$ $y = 13$
