domain of f(x)=0.5(2)^x

domain

f (x) = 0.5 (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

x^{2} - 3

9 - 4 x^{2}

(- 3, 2), (2, - 2)

f (x) = - \frac{1}{2} (x - \frac{1}{3})^{2} - \frac{3}{2}

(x - 2)^{3}
