domain of f(x)=10-x^{-2}

domain

f (x) = 10 - x^{- 2}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

f (x) = \frac{x - 9}{x ^{2} - 17 x + 72}

lo g_{x + 3} (5)

5 x^{4} - 3 x^{2} + 7

f (x) = \frac{x - 4}{x ^{2} - 7 x + 12}
