How to find the asymtope of a function
Darya [45]
Asymptote at x = 3 and a horizontal asymptote at y = 1. The curves approach these asymptotes but never cross them. The method used to find the horizontal asymptote changes depending on how the degrees of the polynomials in the numerator and denominator of the function compare.

Which equation could have been used to create this function table?
ratelena [41]
For multiple-choice questions, it is often faster to check the answers than to try to figure out what the answer should be.

Only selections (A) and (D) match the first entry in the table.
Of those, only selection (A) matches the second entry in the table.

The appropriate choice is ...
   (A) y = x + 9

Is this number written in scientific notation? 33.4 × 10 − 2 Group of answer choices Yes it is in scientific notation No it is n
Rus_ich [418]

Answer:

<h3>No it is not in scientific notation</h3>

Step-by-step explanation:

The standard form of a scientific notation is expressed as:

A * 10^n where;

A is any number from between 1 and 10

Given the expression 33.4 × 10^ − 2

Comparing with the general formula, you will see that A = 33.2

Since the value of A does not fall between 1 and 10, hence the expression 33.4 × 10^-2 is not a scientific notation
