## 1.2 Power Functions

#### Introduction to Power Functions

- Power functions are functions with the form f(x)=x^{n}, where n is a rational number.
- Some examples of power functions are:

f(x)=x^{2},\ f(x)=x^{4},\ f(x)=x^{\frac{1}{4}},\ f(x)=x^{-5},\ f(x)=x^{\frac{1}{3}}

- The expression x^n is read as: ‘x to the power of n’.
