Answer:
B
Step-by-step explanation:
As x gets bigger or smaller, y approaches negative infinity
The function can be expressed as a rational function is
.
We have to determine
Which of the following is written as a rational function?
According to the question
A rational function is a function that can be expressed as the quotient or ratio of two polynomial functions, where the polynomial in the denominator must have a degree of at least 1.
A rational function can be expressed as;

Then,
The required rational function is expressed as;

Where p(x) is (x-5) and g(x) is 3x.
Therefore,
The function is,

Hence, the function can be expressed as a rational function is
.

We know that
if <span>4 electricians can complete a job in 8 hours
then
</span>100% of a job -------> 8 hours
x------------------> 1 hour
x=100/8----> x=12.5%
divide by 4 electricians
12.5%/4-----> 3.125%
that means each electrician can complete 3.125% of a job in 1 hour
therefore
3 electricians-----> 3*3.125%----> 9.375% in 1 hour
so
9.375%-----------> 1 hour
100%--------------> x
x=100/9.375----> x=10.67 hours
the answer is
10.67 hours
900. You round up, because it is above 850. :-)
