domain of f(x)=f(x)=-2x^2-1

domain

f (x) = f (x) = - 2 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) = \frac{ln ( t )}{t}

\frac{x ^{2} - 9}{x + 1}

f (x) = \frac{1}{4 x ^{2} ( x ^{2} - 3 ) ^{2}}

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

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

What is the domain of f(x)=f(x)=-2x^2-1 ?
The domain of f(x)=f(x)=-2x^2-1 is -infinity <x<infinity
