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

domain

f (x) = \frac{1 + 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

\frac{x}{x + 1}

(6, 3), (10, - 7)

f (x) = \frac{3 x + 5}{7 x + 4}

f (x) = x + 4 - x

12 - x

What is the domain of f(x)=(1+x^2)/4 ?
The domain of f(x)=(1+x^2)/4 is -infinity <x<infinity
