Question

the maximum and minimum values of the function Y equal to X ki power 3 - 3 x ki power 2 + 6 are

Answer 1

y = x³ – 3x² + 6

Domain of the function: -∞ ≤ x ≤ ∞

The range of the function: -∞ ≤ f(x) ≤ ∞

∴ The minimum value = -∞

The maximum value = ∞

See the graph below:

Local maximum is at (0, 6)

Local minimum is at (2, 2)
