# Power Functions Exercises

### Example 1

Find the derivative of the function f(x) = x2, using the limit definition of the derivative.

### Example 2

Find the derivative of the function f(x) = x3, using the limit definition of the derivative.

### Example 3

Find the derivative of the function f(x) = x4, using the limit definition of the derivative.

### Example 4

Now it's time for pattern-finding. We know the following functions and their derivatives:

f(x) = x2   f ' (x) = 2x

f(x) = x3   f ' (x) = 3x2

f(x) = x4   f ' (x) = 4x3

What's the pattern?
