The turning point on the curve \(y = 3x^2 - 9x + 12\) is


Question

The turning point on the curve \(y = 3x^2 - 9x + 12\) is

Options

A) maximum at x = -1.5

B) minimum at x = 1.5

C) maximum at x = 1.5

D) minimum at x = -1.5

The correct answer is B.

Explanation:

\(y = 3x^2 - 9x + 12\)
Finding the derivative or \(dy/dx\) we have
\(6x - 9\).
So \(6x = 9\)
And dividing through by 6,
\(x = 1.5\)
