Until now we have dealt with various calculations of

**functions**and**equations**where x is either in the base or the**exponent**. When x is the**exponent**the**function**is known as an**exponential function**. As with any**function**whatsoever, an**exponential function**may be correspondingly represented on a graph.Likewise, what does an exponential function look like?

**Exponential**Functions. If you think of functions with exponents, you're probably used to seeing something

**like**this. That's the graph of y = x2, and it is indeed a function with an exponent. In an

**exponential**function, the independent variable, or x-value,

**is the**exponent, while the base is a constant.

What is an example of an exponential expression?

**Exponential Expressions**. The use of an

**exponential**is a very convenient way of expressing the repeated multiplication of a number by itself. The

**exponent**is placed to the upper right of the base number and signifies how many times the base term is multiplied by itself.
