domain of f(x)= 2/(x^2+1)

domain

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

- \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

sy mm e t ry x^{2} + 12 x + 6

in t erce pt s f (x) = 6 x^{2} - 5 x - 4

in v erse f (x) = (x - 4)^{2} - 1

r an g e lo g_{5} (x - 6) + 2

p a r i t y f (x) = \frac{4}{x}
