Concepts

A piecewise function is defined as:

$f(x) = \begin{cases} x + 1 & \text{if } x < 3 \\ 7 & \text{if } x \geq 3 \end{cases}$

At $x = 3$ , the graph should show:

A solid dot at $(3,\,4)$ and an open circle at $(3,\,7)$ .

An open circle at $(3,\,4)$ and a solid dot at $(3,\,7)$ .

Solid dots at both $(3,\,4)$ and $(3,\,7)$ .

Open circles at both $(3,\,4)$ and $(3,\,7)$ .
