Limits Gx Bad94D
1. **Statement of the problem:**
We are given the function $$g(x) = 2 - x - \ln{(x-1)^2}$$ defined on the domain $$]1, +\infty[$$. We need to calculate the limits $$\lim_{x \to +\infty} g(x)$$ and $$\lim_{x \to 1^+} g(x)$$.
2. **Recall the formulas and rules:**
- The natural logarithm function $$\ln(x)$$ tends to $$+\infty$$ as $$x \to +\infty$$ and tends to $$-\infty$$ as $$x \to 0^+$$.
- For limits involving logarithms and polynomials, analyze dominant terms.
3. **Calculate $$\lim_{x \to +\infty} g(x)$$:**
$$g(x) = 2 - x - \ln{(x-1)^2} = 2 - x - 2\ln(x-1)$$
As $$x \to +\infty$$, $$x$$ grows without bound and $$\ln(x-1)$$ also tends to $$+\infty$$ but slower than $$x$$.
So,
$$\lim_{x \to +\infty} g(x) = \lim_{x \to +\infty} (2 - x - 2\ln(x-1)) = -\infty$$
because the linear term $$-x$$ dominates.
4. **Calculate $$\lim_{x \to 1^+} g(x)$$:**
As $$x \to 1^+$$, $$x-1 \to 0^+$$, so
$$\ln{(x-1)^2} = 2 \ln(x-1) \to 2 \times (-\infty) = -\infty$$
Thus,
$$g(x) = 2 - x - \ln{(x-1)^2} = 2 - x - 2\ln(x-1)$$
Since $$-2\ln(x-1) \to +\infty$$, and $$2 - x \to 1$$,
Therefore,
$$\lim_{x \to 1^+} g(x) = +\infty$$.
**Final answers:**
$$\lim_{x \to +\infty} g(x) = -\infty$$
$$\lim_{x \to 1^+} g(x) = +\infty$$
