Find the intervals of monotonicity of the quadratic function
\(f(x) = -3x^{2} + 2\).
The function is increasing on \( (- \infty ;0 ] \)
and decreasing on \( [ 0;\infty ) \).
The function is increasing on \((-\infty;2) \)
and decreasing on \( ( 2;\infty) \).
The function is increasing on \(\left(-\infty;\frac23 \right] \)
and decreasing on \( \left[ \frac23;\infty\right) \).
The function is decreasing on its domain.
