Evaluate the limits<br><br>​
julsineya [31]

x > \ln(x) for all x, so

\displaystyle \lim_{x\to\infty} (\ln(x) - x) = - \lim_{x\to\infty} x = \boxed{-\infty}

Similarly, \displaystyle \lim_{x\to\infty} (x-e^x) = - \lim_{x\to\infty} e^x = \boxed{-\infty}

We can of course see the limits are identical by replacing x\mapsto e^x, so that

\displaystyle \lim_{x\to\infty} (\ln(x) - x) = \lim_{x\to\infty} (\ln(e^x) - e^x) = \lim_{x\to\infty} (x - e^x)

You can also rewrite the limands to accommodate the application of l'Hôpital's rule. For instance,

\displaystyle \lim_{x\to\infty} (x - e^x) = \ln\left(\exp\left(\lim_{x\to\infty} (x - e^x)\right)\right) = \ln\left(\lim_{x\to\infty} e^{x-e^x}\right) = \ln\left(\lim_{x\to\infty} \frac{e^x}{e^{e^x}}\right)

Using the rule, the limit here is

\displaystyle \lim_{x\to\infty} \frac{(e^x)'}{\left(e^{e^x}\right)'}  = \lim_{x\to\infty} \frac{e^x}{e^x e^{e^x}} = \lim_{x\to\infty} \frac1{e^{e^x}} = 0

so the overall limit is

\displaystyle \lim_{x\to\infty} (x - e^x) = \ln\left(\lim_{x\to\infty} \frac{e^x}{e^{e^x}}\right) = \ln(0) = \lim_{x\to0^+} \ln(x) = -\infty

The following graph shows the low temperatures for the past six nights. What was the range of temperatures for the six nights?
Kobotan [32]

Answer:

Step-by-step explanation:

highest temperature for past six nights = 34°F

lowest temperature for past six night = 22°F

so, the range of temperature = highest temperature - lowest temperature

                                                 = 34°F - 22°F

                                                 = 12°F

hence , the range of temperature is 12°F
