domain of f(x)=-(12)/(2x-9)

domain

f (x) = - \frac{12}{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) = - 3 (x^{2} + 5)

g (x) = \frac{x ^{2}}{( x - 3 ) ( x + 4 ) ( x + 1 )}

g (x) = \frac{9}{x - 3}

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

\frac{x ^{2} + 1}{x ^{4} + 3 x ^{2} + 1}

What is the domain of f(x)=-(12)/(2x-9) ?
The domain of f(x)=-(12)/(2x-9) is x< 9/2 \lor x> 9/2
