domain of f(x)=x-1

domain

f (x) = 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

(- \frac{1}{3}, \frac{2}{3}), (- \frac{11}{3}, - \frac{8}{3})

(3, 5), (- 1, 5)

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

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

y = 9 x^{2}
