Answer

$f(x)$ appears to have a limit as $x\to1$, which is $0.367879...$

Work Step by Step

$$f(x)=x^{1/(1-x)}$$ (a) The table is shown below. As we can see from 2 tables below, as $x$ gets more decimals and approaches $1$, the value of $f(x)$ also gets more decimals and apparently approaches a value of $0.367879...$ from both sides. Even though, we cannot get an exact value of this number, f(x) still approaches this same value either from the left or the right side as $x\to1$, meaning $f(x)$ appears to have a limit here, which is $0.367879...$ (b) The graph is shown below. Looking at the graph, we confirm that the closer $x$ approaches $1$, the closer $f(x)$ gets to $0.367879...$.
