domain of (2x+1)^2-1

domain

(2 x + 1)^{2} - 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

(4, 2), (- 1, - 13)

f (x) = x - 8

(4.4) (0.4)

f (x) = ln (x) - ln (x - 1)

2 x + 2
