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

(3.2) (7.6)

f (x) = - 4 cos (x + \frac{π}{4})

f (x) = 5 + \frac{4}{3} x

f (x) = \frac{x ^{2} - 4}{3 x ^{2}}

cos (sin (tan (5 x)))
