9-119.

Write a set of equations for the piecewise-defined function shown on the graph at right. Be sure to include the domain for each part of the function. 9-119 HW eTool (Desmos).

Look at the two pieces of the function. Notice the open and closed circles, and the values at $x = 2$.

$f(x)=\begin{cases}x+1, \ x \geq 2\\2x-3, \ x< 2 \end{cases}$
