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

domain

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

- \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

sinh (x)

3 sin (2 x)

x + 16

- 7 x - 4

f (x) = \frac{x ^{2} - 3 x - 4}{x ^{2} - 1}

What is the domain of f(x)=-x^2+18x-1 ?
