serg [7]

Answer:

In the boreal forest the ground thaws more and does not have a permafrost layer. This allows trees to take root. Compose an argument for categorizing mountains and polar regions as terrestrial biomes. Mountains and polar regions have these characteristics and provide land on which certain plants and animals can live.

Which colonies (blue, white, or both) would you want to pick for further analysis to check for the successful cloning of the ant
Setler79 [48]

You should pick both colonies for the further analysis. Colonies are white or blue depending on their possibility to metabolize X-gal product (the blue colonies can metabolize X-gal product, and they encode for lacZgene). Whether it encodes or lacks the lacZ gene, it can still uptake the antithrombin gene and grow on the medium through electroporation.

Choose the items that complete the sentence about the key features of f(x) = 8x. The y-intercept is Choose... , the asymptote is
prisoha [69]

Answer:

I suppose that the equation is:

f(x) = 8/x

(You wrote 8x, this is a linear function, so it has no asymptotes, then I assume that the actual function was 8/x)

The y-intercept is the value such that  f(x) = 0

Notice that there is no value of x such that 8/x = 0  (if the numerator is never zero, then the quotient can't be zero)

So we do not have an y-intercept.

The asymptote:

Here we have four:

if x tends to zero from the negative side, then:

8/x tends to negative infinity.

if x tends to zero from the positive side, then:

8/x tends to positive infinity.

These two asymptotes can be written as:

\lim_{n \to \_-0} \frac{8}{x} = -\infty\\ \lim_{n \to \_+0} \frac{8}{x} = +\infty

We also have two when x tends to plus infinity (and 8/x goes to zero) and when x tends to negative infinity, such that the function tends to zero again, these two can be written as:

\lim_{n \to \infty} \frac{8}{x}  = 0\\ \lim_{n \to -\infty} \frac{8}{x}  = 0

Finally, the range:

The only value that y never reaches (only on limits) is:

y = 0

Then the range is the set of all real numbers except the zero, or:

R :  { x ∈ R / {0} }
