domain of y=x^2-4

Solution

domain

y = x^{2} - 4

Solution

- \infty < x < \infty

+1

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

Popular Examples

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

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

domain of f(x)= 1/(sqrt(x))domain

f (x) = \frac{1}{x}

range of (x-3)/(x^2-1)range

\frac{x - 3}{x ^{2} - 1}

y = x + 2

domain of f(x)= 8/(1-e^x)domain

f (x) = \frac{8}{1 - e ^{x}}
