# Using the limit definition, how do you find the derivative of #f(x)= 2x^2-x#?

##### 1 Answer

#### Explanation:

By limit definition, the derivative of any function is

Now, for this particular question, we have

So, using the derivative definition, we have

Rearranging the equation and separating to have the

In the right side, the second term is simple so we'll directly get it as

Now, since it's not possible to reduce the terms any further, we can finally just take
