domain of (-x+1)/(sqrt(x^2+2))

domain

\frac{- x + 1}{x ^{2} + 2}

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find non-negative values for radicals:

- \infty < x < \infty

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

- \infty < x < \infty

f (x) = - 6 x - 8

f (x) = \frac{x + 3}{x ^{2} - 2 x - 8}

f (x) = (5 x - 25)^{- 2}

t - 4

f (x) = 5 x - 4 x - \frac{1}{x}
