Graph the exponential function y = 3^x

Solution:

The function y = 3^x is an exponential function, the graph of which is shown below:

The domain of the function y = 3^x is x(-∞ to +∞) and the range is y(0 to +∞).

As the value of x tends towards -∞ the value of y approaches zero which is on the LHS of the graph of the function.

As x approaches +∞ the function y also approaches +∞.

Graph the exponential function y = 3^x

Summary:

The graph of the exponential function y = 3^x is plotted and the domain of the function is (-∞ to +∞) and the range is (0 to +∞).
