domain of f(x)=25-x^2

domain

f (x) = 25 - x^{2}

- \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) = \frac{( e ^{x} )}{1 - e ^{x}}

x - \frac{1}{x}

f (x) = - 3 x^{2} + 9 x + 5

- 2 x + 10

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