What’s an expotential function

Overview of the exponential function

The exponential function is one of the most important functions in mathematics (though it would have to admit that the linear function ranks even higher in importance). To form an exponential function, we let the independent variable be the exponent. A simple example is the function

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
