Graph $f(x) =\left\{ \begin{array} { l } { ( x - 2 ) ^ { 2 } \text { for } x \geq 0 } \\ { 3 x + 4 \text { for } x < 0 } \end{array} \right.$ . Is the function continuous at $x=0$ ? Explain.

Hint:

Graph a parabola with a vertex at $(0,2)$ for $x\ge0$ .
Graph a line with a slope of $3$ and a $y$ -intercept of $4$ for $x<0$ .
