Find the intervals of monotonicity of the quadratic function

f (x) = 2 x^{2} + 3

.

The function is increasing on

[0; \infty)

and decreasing on

(- \infty; 0]

.

The function is increasing on

(3; \infty)

and decreasing on

(- \infty; 3)

.

The function is increasing on

[- \frac{3}{2}; \infty)

and decreasing on

(- \infty; - \frac{3}{2}]

.

The function is increasing on its domain.
