# 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

### Explanation:

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