A horizontal asymptote means some value the function will approach as x becomes unbounded (infinity or negative infinity).
As x goes to infinity in this function, y also goes to infinity. So this can't be it. It has to approach a definite value.
How about negative infinity? As x goes to negative infinity, y goes to 3 (5^-x goes to 0). y = 3 is your asymptote

The function y = 5*(2^x) + 3 has a horizontal asymptote where?
Limit as xâ -â of {5*(2^x) + 3} = 5*0 + 3 = 3
The horizontal asymptote is the line y = 3.
