Smaller one is x=2 , Larger one is x=8
1 Identify the critical numbers of the function
, which are the values of x where the first derivative of the function is zero or undefined
2 Find the derivative of the function using the power rule for derivatives, which states that the derivative of is
3 Apply the power rule to the given function
to get the derivative
4 Set the derivative equal to zero and solve for x to find the critical numbers. The equation can be simplified by dividing each term by 6 to get
5 Factor the quadratic equation to find the values of x that satisfy the equation. The factors are (x-2)(x-8)=0 , which gives us the solutions x=2 and x=8
6 Conclude that the smaller critical number is x=2 and the larger critical number is x=8
