Which equation describes a relationship such that x = 1 must be excluded from the domain?

1 answer:

7 0

Answer:

First choice

Step-by-step explanation:

The domain refers to all possible values that could be plugged into the function.

The first choice, $\frac{1}{1-x}$ , will not be valid for the value $x=1$ because when $x$ is 1 the denominator becomes zero.

Division by zero will produce an undefined result, which would be represented by an asymptote when graphing the function.

I would have to guess a bar graph, because it would calculate and compare the amounts to each person, but that would just be my guess.

Hope this helps, if not, comment below please!!!

$24.4\% = \frac{24.4}{100}=\frac{244}{1000}=\frac{61}{250}$

As a decimal fraction:
$24.4\% = \frac{24.4}{100}=\frac{244}{1000}=0.244$
