Answer
Explanation:
Step1: Find $\lim_{x\to - 1^{-}}f(x)$
When $x\to - 1^{-}$, we use the part of the function $f(x)=11$ (since $x < - 1$ for this left - hand limit). So $\lim_{x\to - 1^{-}}f(x)=11$.
Step2: Find $\lim_{x\to - 1^{+}}f(x)$
When $x\to - 1^{+}$, we use the part of the function $f(x)=-x + 10$ (since $-1\leq x<8$). Substitute $x=-1$ into $-x + 10$, we get $-(-1)+10=11$. So $\lim_{x\to - 1^{+}}f(x)=11$.
Step3: Find $\lim_{x\to - 1}f(x)$
Since $\lim_{x\to - 1^{-}}f(x)=\lim_{x\to - 1^{+}}f(x)=11$, then $\lim_{x\to - 1}f(x)=11$.
Step4: Find $\lim_{x\to 8^{-}}f(x)$
When $x\to 8^{-}$, we use the part of the function $f(x)=-x + 10$ (since $-1\leq x<8$). Substitute $x = 8$ into $-x + 10$, we get $-8 + 10=2$. So $\lim_{x\to 8^{-}}f(x)=2$.
Step5: Find $\lim_{x\to 8^{+}}f(x)$
When $x\to 8^{+}$, we use the part of the function $f(x)=10e^{x - 8}$. Substitute $x = 8$ into $10e^{x - 8}$, we get $10e^{8 - 8}=10$. So $\lim_{x\to 8^{+}}f(x)=10$.
Step6: Find $\lim_{x\to 8}f(x)$
Since $\lim_{x\to 8^{-}}f(x)=2$ and $\lim_{x\to 8^{+}}f(x)=10$, and $\lim_{x\to 8^{-}}f(x)\neq\lim_{x\to 8^{+}}f(x)$, then $\lim_{x\to 8}f(x)$ does not exist (DNE).
Answer:
- $11$
- $11$
- $11$
- $2$
- $10$
- DNE
