To find the extrema of the function, we need to take the derivative and set it equal to 0. 
Taking the derivative of the given function, we get: 
11ea8970_6a4c_1cc0_861b_2efaeeb5ef0e_TB1301_11 
Setting this equal to 0 and solving for x will give us the critical point. 
11ea8970_6a4c_50b5_861b_58ac9f7a9d59_TB1301_11 
Since this critical point is negative, we can eliminate choices A, B, and E since they all have positive roots. 
The only answer choice with a negative root is D. Therefore, the answer is D.
