domain of f(x)=x^2-7x-18

domain

f (x) = x^{2} - 7 x - 18

- \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

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

\frac{5 x}{4 x - 1}

f (x) = \frac{28}{x ^{2} + 7 x - 98}

\frac{5 x}{4 x - 2}

x + 2 - 2 x + 3
