domain of f(x)=2^x-7

domain

f (x) = 2^{x} - 7

- \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{x}{3 x + 5}

f (x) = 12 x lo g_{10} (x + 6)

f (x) = \frac{1}{2 x ^{2} + x - 6}

f (x) = \frac{x + 5 - 1}{2}

f (x, y) = e^{y}
