Answer:
[tex]R=(-2,\infty)[/tex]
Explanation:
We need to plot the function to have an understanding of the range.
The range of a function is the values that f(x) can take (the values in the y-axis).
The graph is the following:
We can see that in the y-axis (the vertical axis) the function takes values from -2 and upwards.
The red line represents the range, wich is:
[tex]R=(-2,\infty)[/tex]
