Analyze the end behavior of both functions.
igor_vitrenko [27]

Answer:

The end behaviour of all the functions is same ie they all tend to zero.

Step-by-step explanation:

In every option the function f(x)is a linear function which tends to infinity at the  end(as x tends to infinity).Now the function g(x)in every option is just the reciprocal of f(x).As we all know

\lim_{n \to \infty} f(x)=∞

then

\lim_{n \to \infty} 1/f(x)=0

Observing the histogram, frequency proportions, and normal probability plot based on the data set, below, of weights of hummingb
Serga [27]

Answer:

Normally Distributed.

Explanation:

After plugging all those numbers into a calculator you can see that the graph isn't left skewed, making both "left skewed" and "all of the above" <em>not an answer.</em> "correlated with a second set of data" is also <em>wrong</em> since there was no second set of data given. That leaves you between "uniformly distributed" and "normally distributed" This graph doesn't show a uniformly distributed graph, which leaves you with the final answer, normally distributed.
