Answer
-2
Work Step by Step
Consider the information provided and study the graph carefully,
Here, both the equations have the functions with x coordinate as the variable. It show that the given number in the form of function have the value of the x coordinate.
Locate the value of $y$for the respective plot on the graph:
$\begin{align}
& f\left( -1 \right)=1 \\
& g\left( -1 \right)=-3
\end{align}$
To find the provided number, substitute the value of$f\left( -1 \right)$as 1 and $g\left( -1 \right)$as$-3$in the$f\left( -1 \right)+g\left( -1 \right)$:
$\begin{align}
& f\left( -1 \right)+g\left( -1 \right)=1+\left( -3 \right) \\
& =-2
\end{align}$
Thus, the value of the number is$-2$.
