domain of f(x)=(6x+7)/(9x+2)

domain

f (x) = \frac{6 x + 7}{9 x + 2}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - \frac{2}{9}

The function domain

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

f (x) = ln (x) + ln (1 - x)

(1.1) (4.4)

f (x) = 4 sin (3 π - 2 π x) - 7 π

y = \frac{x + 2}{1 - 2 x}

4 x^{2} + 3

What is the domain of f(x)=(6x+7)/(9x+2) ?
The domain of f(x)=(6x+7)/(9x+2) is x<-2/9 \lor x>-2/9
