The lowest value of the range of the function shown in the graph is -2.
<h3>What is range of a function?</h3>
The range of a function is the set of its possible output values.
In other words, the range of a function is the complete set of all possible resulting values of the dependent variable (y), after we have substituted the domain or independent variables.
The range value are the y values of the graph shown.
Therefore, the lowest value of the range of the function shown on the graph is -2.
