Question

How to graph an exponential function

Answer 1

Step-by-step explanation:

Exponential function is given by general form $y=ab^x$

Where a and b are constants.

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

$y=1*2^x$

or $y=2^x$

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

$y=2^x=2^1=2$

Hence point is (1,2)

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