For this case, we must find the equation of the line.
The generic equation of the line is:

The slope of the line is:

Substituting values we have:

Rewriting:

We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:

Rewriting the equation:

For 20 visits, we evaluate the equation when x = 20.
We have then:

Answer:
Exponentials and logarithms are inverses of each other.
Step-by-step explanation:
Exponentials and logarithms are inverses of each other.
For logarithmic function:
Domain =
, Range = 
Vertical asymptote is y - axis.
x - intercept is (1,0)
For exponential function:
Domain =
, Range = 
Horizontal asymptote is x - axis.
y- intercept is (0,1)
Both exponential and logarithmic functions are increasing.
For example:
Solve: 


I think it's a acute but I'm not sure
