domain of f(x)=(9x-9)/(2x+7)

domain

f (x) = \frac{9 x - 9}{2 x + 7}

x < - \frac{7}{2} or x > - \frac{7}{2}

Interval Notation

(- \infty, - \frac{7}{2}) \cup (- \frac{7}{2}, \infty)

Solution steps

Find undefined (singularity) points:

x = - \frac{7}{2}

The function domain

x < - \frac{7}{2} or x > - \frac{7}{2}

y = \frac{3 x}{x ^{2} + 25}

f (x) = - 2 x - 3

ln (x^{2} - x - 6)

y^{2} = + 25

f (x) = 13 x^{4} - 78 x^{2}

What is the domain of f(x)=(9x-9)/(2x+7) ?
The domain of f(x)=(9x-9)/(2x+7) is x<-7/2 \lor x>-7/2
