domain of 2x-78

domain

2 x - 78

- \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

y = 3^{x} + 2

f (x) = 1 + x + x^{3}

f (x) = \frac{x - 1}{x ^{2} - 9}

(x^{2})^{2}

\frac{2 x + 8}{- 8 x + 4}
