How to graph an exponential function: Identify the exponential function in the form y=a⋅b x . Determine the y-intercept by evaluating the function at x=0. Find a few other points by choosing different x-values and solving for y. Plot the points on a coordinate plane. Draw a smooth curve through the points to represent the exponential function. Note any asymptotes, typically the horizontal line y = 0 for basic exponential functions. Label the graph appropriately.
