domain of f(x)=(4x)/(2x+9)

domain

f (x) = \frac{4 x}{2 x + 9}

x < - \frac{9}{2} or x > - \frac{9}{2}

Interval Notation

(- \infty, - \frac{9}{2}) \cup (- \frac{9}{2}, \infty)

Solution steps

Find undefined (singularity) points:

x = - \frac{9}{2}

The function domain

x < - \frac{9}{2} or x > - \frac{9}{2}

f (x) = - x^{4} - 6 x^{3} + 42 x^{2} + 12 x - 80

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

x - 5 y = 30

f (x) = x - 2

f (x) = \frac{x ^{2} + 3 x - 54}{x ^{2} - 9}

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