domain of f(x)=4-x^2

domain

f (x) = 4 - 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

\frac{2 x + 11}{3 x + 19}

2 x - 3 y = \frac{7}{5}

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

f (x) = \frac{4}{11 - 2 x}

3 - tan (\frac{x}{2} + \frac{π}{3})
