domain of f(x)=e^x+2e^{2x}

domain

f (x) = e^{x} + 2 e^{2 x}

- \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) = x^{2} + 2 x - 1

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

- 2 y = 14 - 6 x

3 - 4 sin (\frac{2}{3} (x - 1))

y = 4 x - 4
