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

domain

f (x) = 7 - 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{3}{5 x ^{5}}

f (x) = \frac{9 x - 9}{2 x + 7}

y = \frac{3 x}{x ^{2} + 25}

f (x) = - 2 x - 3

ln (x^{2} - x - 6)
