Exponential equation are functions defined by 
The equation that could represent Rainey graph must take the form 
<h3>How to determine the equation</h3>
An exponential equation is represented as:
Where:
- a represents the initial value
- b represents the rate
The initial value (a) is 15.
So, the equation becomes
The graph is not given;
So, the equation cannot be determined.
Assume that the rate is 2.
Then the function would be:

5 possibly cause the state of numbers have a typical pattern! NOT SURE THO!!! but a little help! <3 goodluck.
When you multiply two complex numbers given in polar form, the argument of the product is the sum of the arguments of the factors. Meanwhile, the modulus of the product is the product of the moduli of the factors.
In this case, you'd have
and the modulus would simply be
. Since
we would expect the final product to fall in the first quadrant.
Is there more to this problem? By saying f(4), you'd be inputting a 4 for every variable x. There is not enough info here to answer the question.
