domain of X^2+4

domain

X^{2} + 4

- \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) = x + 3

y = - 3 x^{2} + 48 x - 195

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

f (x) = \frac{3}{5 x ^{5}}

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