Answer:
The correct option is 1. The rate of change is 2%.
Step-by-step explanation:
The general growth function is
.... (1)
Where, P is initial value and r is rate of change.
The given exponential function for compounding interest is
The given function can be written as
..... (2)
From (1) and (2) we get
In % it can be written as
Therefore the correct option is 1. The rate of change is 2%.

Answer:
x < -4 ∪ x > 4
Step-by-step explanation:
The absolute value function is shifted down 3 units. The solution space is values of x where y = |x|-3 is greater than 1. The solution is shown in red in the attachments, and the left and right (dashed) sides of the inequality are shown in blue.

I personally prefer to rewrite the inequality so the comparison is to <em>zero</em>. That is done in the second attachment, which rewrites it to ...
|x| -4 > 0
by subtracting 1 from both sides. It is often easier to read the values of x-intercepts than it is to read the coordinate values where lines cross each other.
