domain of (4x+9)/((3x+9)^2)

domain

\frac{4 x + 9}{( 3 x + 9 ) ^{2}}

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

x^{2} + 6 x + 8

f (x) = \frac{5 x}{x + 5}

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

\frac{3 x + 54}{3 ^{x} - 81} + 19 - x^{4}

y = \frac{x ^{2}}{4 - x}

What is the domain of (4x+9)/((3x+9)^2) ?
The domain of (4x+9)/((3x+9)^2) is x<-3\lor x>-3
