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

domain

f (x) = \frac{( x + 1 ) ^{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) = 2 (5)^{x} + 3

f (x) = - 9 y^{2} - 121 + 5 x^{2} + 54 y - 10 x = 0

\frac{( x - 6 )}{x ^{2} - 36}

f (x) = \frac{x + 3}{x ^{2} - 5}

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

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