domain of 1/(11.25x)-1/90

domain

\frac{1}{11.25 x} - \frac{1}{90}

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

y = (1 - x^{2})^{x}

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

x (x + 3)^{\frac{2}{5}}

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