domain of f(x)=5x^2+25

domain

f (x) = 5 x^{2} + 25

- \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

- 9 - x

f (x) = x (x + 2) (x - 2)

f (x) = \frac{1}{2} tan (t)

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

f (x) = (\frac{x + 4}{x ^{2} - 16})
