<u>Answer-</u>
<em>The domain of is, </em>
<em></em>
<u>Solution-</u>
For , there can not have a log to any value of x, which is either negative or 0.
So domain of log x is,
Equating 2(x-1) to 0, we can get the domain of the given function, hence
Therefore, domain of g(x) is any real number greater than 1, i.e
Answer:
B.
Step-by-step explanation:
We are given the function:
Which represents the population of a certain city <em>x </em>years after it was founded.
The y-intercept is the y-value when <em>x</em> = 0. So:
If <em>x </em>= 0, this means that zero years have passed since the city was founded.
So, the y-intercept represents the initial amount of people when the city was founded (in this case, there were 7870 people).
The correct answer is B.
