Full solution

Q. Determine the value of

y

, if

x

is

-4

.

\newline

y=x^{2}+4

\newline

Answer:

Substitute $x$ with $-4$ : We are given the function $y = x^2 + 4$ and need to find the value of $y$ when $x$ is $-4$ . To do this, we substitute $x$ with $-4$ into the equation and calculate the value of $y$ . $y = (-4)^2 + 4$
Calculate square of $-4$ : Calculate the square of $-4$ . $(-4)^2 = 16$
Add $4$ : Add $4$ to the result of the square of $-4$ . $\newline$ $y = 16 + 4$
Perform addition: Perform the addition to find the value of $y$ . $y = 20$
