Answer:

Step-by-step explanation:

Let's try 4 first.

4^8 is 65536, and 4^5 is 1024.

65536 / 1024 is 64, so 4 is not an answer.

And, let's try 3.

3^8 is 6561, and 3^5 is 243.

6561 / 243 is 27, so 3 is the answer!

Find the limit of the function algebraically. (2 points) limit as x approaches zero of quantity x squared plus two x divided by

DIA [1.3K]

Answer:

DNE

Step-by-step explanation:

$\lim_{x \to \0} \frac{x^{2} +2x}{x^{4} }$

As you can see in the picture I attached to this, that as the limit goes to zero from the negative side, it approaches -∞ and from the positive side, it approaches ∞ . hence, the limit doesn't exist.

To show this algebraically, you have to imagine how a number divided by zero looks like, Just know the graph of 1/x and see how the limit to zero doesnot exist. I hope this helps!
