domain of y=x^2-5

domain

y = x^{2} - 5

- \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

(0, 2), (5, 0)

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

y = - x + \frac{1}{3}

f (x) = \frac{5 x ^{2} - 19 x - 4}{2 x ^{2} - 2}

\frac{- 3 x ^{2} - x + 3}{x ^{2} - 1}
