FinnZ [79.3K]3 years ago

<u>From the problem statement:</u>

n = "a number"

seven less than twice a number is -1

* now i'll underline the changes made by interpreting the way the question was written:

<u>7</u> less than <u>two times</u><u> </u><u>n</u> is -1

7 less than <u>2*</u><u>n</u> <u>equals</u> -1

<u>take away 7 from</u> <u>2n</u> <u>=</u> -1

2n <u>take away 7</u> = -1

2n <u>-</u> 7 = -1

<u><em>2n - 7 = -1</em></u>

<u><em>answer is:  (A)</em></u>

Which of the following describes the end behavior of<br> f(x) = (1/2)^x
NARA [144]

Answer:

as x approaches infinity, f(x) approaches 0

as x approaches -infinity, f(x) approaches infinity

Step-by-step explanation:

we can observe that 1/2 < 1 and since it's being exponentiated, the f(x) gets smaller and smaller as x gets bigger.

For example, f(0) = 1, f(1) = 1/2, f(2) = 1/4

so, as x approaches an infinitely large number, f(x) gets closer and closer to zero.

this is the opposite as x approaches a negatively large number. following exponential rules, 1/2^(x) = 2^x for all x < 0. therefore as x approaches negative infinity, f(x) approaches infinity.

in this case, f(-1) = 2, f(2) = 4, f(3) = 8
