Take the derivative of that.

Remember, the derivative of a function is the slope of the function.

Okay so deriv is 6x-3

Set that equal to zero and solve for the **critical points**. You get 1/2 Now you have to pick any number above and below 1/2 for x (Do 0 and 1 to be easy).

If your answer is positive, that means it is increasing. Negative is decreasing.

6(0)-3 = -3 So up until 1/2 your function is decreasing.

6(1)-3 = 3 After 1/2 your function is increasing.

Also, if you plugged your original function into a graphing calculator you could easily just see where it's decreasing/increasing.
