domain of f(x)=2*3^x-1

domain

f (x) = 2 \cdot 3^{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

f (x) = 5 x - 2

x^{2} + 2, x \geq 0

f (x) = - x^{2} + 8 x - 11

f (x) = x + 1 + \frac{2}{x}

f (x) = 2 x^{2} - 3 x + 5
