Answer:
Domain = x E R
Step-by-step explanation:
Since an exponential function has no restriction on the "x" value, its domain can range from anywhere on the plane of "x."
When you write a function in the form
, y is the dependent variable, and x is the independent variable.
So, if b is the independent variable, it means that we have to solve the expression for r.
To do so, we perform the following steps: start with

Add 12 to both sides

Divide both sides by 4:

So, we wrote the expression in the form
, which means that r is the dependent variable and b is the independent variable, as requested.
