Question 1206565



{{{y= -(3)^x }}}

 
An asymptote is a line that the curve of a graph approaches, but never reaches. An asymptote can be a vertical line or a horizontal line.

An exponential function has a horizontal asymptote. A general equation for a horizontal line is: 

{{{y=c}}}

The horizontal asymptote of an exponential function of the form {{{y=a(b)^x}}} is the  {{{x}}}-axis or the line {{{y=0}}}.
