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

domain

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

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

\frac{7 a}{( a + 1 ) ( a - 4 )}

y = lo g_{4} (x + 3)

y = \frac{1}{3 ^{x}}

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

f (x) = \frac{x + 3}{x}

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