How to graph an exponential function

Step-by-step explanation:

Exponential function is given by general form

Where a and b are constants.

say a=1 and b=2 then we can write function as :

or

To graph this or any exponential function, we just need to find some points then join them by a curved line.

Like plug x=0, 1, 2,... into above function and find points:

plug x=1

Hence point is (1,2)

Find more points similarly then graph them to get the graph as shown below:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
