Answer

Explanation:

Step1: Find right - hand limit

For $x\to0^{+}$, $f(x)=3 + x^{2}$. Substitute $x = 0$ into $3 + x^{2}$. $\lim_{x\to0^{+}}f(x)=\lim_{x\to0^{+}}(3 + x^{2})=3+0^{2}=3$

Step2: Find left - hand limit

For $x\to0^{-}$, $f(x)=3 - x^{2}$. Substitute $x = 0$ into $3 - x^{2}$. $\lim_{x\to0^{-}}f(x)=\lim_{x\to0^{-}}(3 - x^{2})=3-0^{2}=3$

Step3: Find overall limit

Since $\lim_{x\to0^{+}}f(x)=\lim_{x\to0^{-}}f(x)=3$, then $\lim_{x\to0}f(x)=3$.

Step4: Find $f(0)$

When $x = 0$, use the part of the function where $x\leq0$, so $f(0)=3-0^{2}=3$

Answer:

(A) A. $\lim_{x\to0^{+}}f(x)=3$ (B) A. $\lim_{x\to0^{-}}f(x)=3$ (C) A. $\lim_{x\to0}f(x)=3$ (D) A. $f(0)=3$
