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 shows that the given numbers in the form of function have the value of the x coordinate.
Locate the value of $y$for the respective plot on the graph:
$\begin{align}
& f\left( 1 \right)=3 \\
& g\left( 1 \right)=-5
\end{align}$
To find the provided number, substitute the value of$f\left( 1 \right)$as 3 and $g\left( 1 \right)$as$-5$in the$f\left( 1 \right)+g\left( 1 \right)$:
$\begin{align}
& f\left( 1 \right)+g\left( 1 \right)=3+\left( -5 \right) \\
& =-2
\end{align}$
Thus, the value of the number is$-2$.
