domain of f(x)=(2y-9)/(8y+9)

domain

f (x) = \frac{2 y - 9}{8 y + 9}

y < - \frac{9}{8} or y > - \frac{9}{8}

Interval Notation

(- \infty, - \frac{9}{8}) \cup (- \frac{9}{8}, \infty)

Solution steps

Find undefined (singularity) points:

y = - \frac{9}{8}

The function domain

y < - \frac{9}{8} or y > - \frac{9}{8}

3 (x + 2)^{2} - 6

f (x) = x - 5 - 5

f (x) = 1 + tan^{2} (x)

f (x) = x^{2} - 4 x + 7

f (x) = 12 - 2 x

What is the domain of f(x)=(2y-9)/(8y+9) ?
The domain of f(x)=(2y-9)/(8y+9) is y<-9/8 \lor y>-9/8
