√80 because the absolute value for complex numbers of the form a+bi are evaluated as √a²+b²
The exponential function is 
<h3>How to determine the equation?</h3>
An exponential function is represented as:
y = b^x
Where b represents the base.
The base is given as:
b = 12
So, we have:
y = (12)^x
It is vertically compressed by a factor of 1/8.
So, we have:
y = 18(12)^x
When reflected across the y-axis, we have:

The horizontal asymptote is y = 2.
So, we have:

It passes through the point (-3, 4).
So, we shift the function to the right by 4 units

Express as a function

Hence, the exponential function is
