Question

Write the function shown in the graph.

Answer 1

You can see that the function is constantly equal to 3 if x is less than -2 (included). So, we have

$f(x)=3$ if [/tex] x\leq -2[/tex]

Similarly, the function is constantly 1 if x is less than -2 (excluded). So, we have

$f(x)=1$ if [/tex] x> -2[/tex]
