domain of f(x)=4x^2+1

domain

f (x) = 4 x^{2} + 1

- \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) = - sin^{2} (x) + 1

f (x) = \frac{2 x + 8}{3 x + 18}

1 0^{x}

f (x) = \frac{1 - x - 4}{x ^{2} - 1}

f (x) = 5 x - 4 - x^{2}
