domain of f(x)=3x^2+2

domain

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

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

(5, 10.388), (7, 13.312)

(6, - 9), (5, - 4)

f (x) = \frac{2 x + 1}{x - 1}

f (x) = (x^{2} - 1)^{2} - 1

f (x) = \frac{1}{2} x^{2}
