domain of f(x)= 1/(x^2-18x+90)

domain

f (x) = \frac{1}{x ^{2} - 18 x + 90}

- \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

(- 2.2) (3)

9 x - 7 y = - 7

\frac{2 x - 3}{x ^{2} - 5 x + 4}

f (x) = x^{\frac{3}{4}} - 9 x^{\frac{1}{4}}

- x + 3 - 2
