Select the correct answer.What is the equation of the asymptote for this function?f(x)= (1/2)^x+ 3

Given the equation:
[tex]f(x)=(\frac{1}{2})^x+3[/tex]As (x) goes to (∞), the value of f(x) will be:
[tex]f(x)=(\frac{1}{2})^{\infty}+3=0+3=3[/tex]So, the equation of the asymptote is: y = 3
The answer will be option D. y = 3
