domain of (x-5)^2-4

domain

(x - 5)^{2} - 4

- \infty < x < \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 + 2

f (x) = \frac{x ^{2} - 25}{x ^{2} + 4 x + 3}

\frac{x ^{2} + 4 x}{6 - x}

f (x) = e^{x} + 4

f (x) = \frac{2 x - 6}{x + 9}
