Answer:
10
Step-by-step explanation:
<h2>
Answer:</h2>
We have the following function:

The graph of this function has been plotted below. So lets analyze each statement:
<h3>1. The function is always increasing.
</h3><h3>False</h3>
As you can see x increases from -∞ to 0 and decreases from 0 to +∞
<h3>2. The function has a domain of all real numbers.
</h3><h3>False</h3>
The function is undefined for
since x is in the denominator.
<h3>3. The function has a range of {yl-
</h3>
Statement is unclear but the range is the set of all real numbers except zero.
<h3 /><h3>4. The function is a reflection of y = 3.
</h3><h3>False</h3>
The function is a reflection in the x axis of the function 
<h3>5. The function passes through the point (3,-27).</h3><h3>False</h3>
This is false since:

Note. As you can see those statements are false, so any of them is true, except item 3 that is unclear.
Answer:
n(t) = 101010(3^t)
Step-by-step explanation:
The initial number of people who knew about it is;
n(0) = 101010
The number of people who will have known in a day's time;
n(1) = 101010(3)
The number of people who will have known in 2 day's time;
n(2) = 101010(3)(3) = 101010(3^2)
The number of people who will have known in 3 day's time;
n(3) = 101010(3)(3)(3) = 101010(3^3)
Therefore, the total number n(t) of people who know about the celebrity proposing t days after the celebrity proposes becomes;
n(t) = 101010(3^t)
X=1 because -7 times 1 = -7
