In this lesson we are going to take a look at the power rule, deriving some instances of the power rule and then using it to different shapes and functions. In calculus, the power rule is used to differentiate functions of the form f(x)=x^r, whenever r is a real number. Since differentiation is a linear operation, polynomials can also be differentiated using this rule. So, first, we are going to give the power rule in general which will be used all the time through calculus. Then we will see two additional equations that will give us the power rule for function with constant and power rule for sum/difference of two functions.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
