domain of f(x)=6+x^2

domain

f (x) = 6 + x^{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

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

f (x) = \frac{x + 3}{x ^{2} + 4 x - 5}

f (x) = \frac{x - 5}{x - 4 x}

f (x) = - x^{2} - 4 x - 5

f (x) = \frac{x ^{2}}{x - 1} + ln (4 - ∣ 2 x + 1 ∣)
