Answer
A.
Work Step by Step
We know that the exponential function is an increasing function and the domain of an exponential function is $(-\infty,\infty)$. The y-axis will be a horizontal asymptote as $-x-\infty$.
The graph in A is increasing and as $-x-\infty$, the horizontal asymptote is the y-axis.
Thus, the graph that matches with the given equation is A.
