Final answer:
To find the relative minima of the function y = x⁴ - 8x³, we need to find the derivative, set it equal to zero, and solve for x. The relative minima of the function are x = 0 and x = 6.
Step-by-step explanation:
To find the relative minima of the function y = x⁴ - 8x³, we need to first find the derivative of the function and then find where the derivative equals zero.
Step 1: Find the derivative of y = x⁴ - 8x³.
The derivative of y = x⁴ is 4x³, and the derivative of y = -8x³ is -24x². So, the derivative of y = x⁴ - 8x³ is 4x³ - 24x².
Step 2: Set the derivative equal to zero and solve for x.
4x³ - 24x² = 0
4x²(x - 6) = 0
x = 0 or x = 6
Thus, the relative minima of the function y = x⁴ - 8x³ are x = 0 and x = 6.
