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

domain

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

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

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

f (x) = \frac{1 + 9 x}{5 - 4 x}

(- 5.4) (7.2)

What is the domain of f(x)=x^2+2x+1 ?
