18. Find the limits with a table, then check your answer by graphing the function. Find lim f(x) \text { and } \lim _{x \rightarrow 1^{+}} f(x) \text { where } f(x)=\left\{\begin{array}{ll}

3 x-6 & \text { if } x<1 \\

x^{2}-3 & \text { if } x>1^{\circ}

\end{array}\right. \text { A) } \lim _{x} f(x)=-3 ; \lim _{x} f(x)=-2 \text { B) } \lim _{x \rightarrow \mathbb{C}} f(x)=-2 ; \lim _{x \rightarrow 1^{+}} f(x)=-3 \lim _{x \rightarrow \mathbb{T}} f(x)=3 ; \lim _{x \rightarrow \mathbb{I}^{+}} f(x)=2 \lim _{x \rightarrow \top} f(x)=2 ; \lim _{x \rightarrow 1^{+}} f(x)=3
