To find the vertical asymptote of an exponential function, we need to consider the behavior of the function as the input approaches positive or negative infinity.

For an exponential function of the form f(x) = a^x, where 'a' is a positive constant, there is no vertical asymptote. The graph of such a function will approach but never touch the x-axis as x approaches negative or positive infinity.

However, if we have an exponential function of the form f(x) = a^x + b, where 'a' is a positive constant and 'b' is a real number, there is still no vertical asymptote. The graph of this function will also approach but never touch the x-axis as x approaches negative or positive infinity.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
