domain of (x-3)/(4+5x)

domain

\frac{x - 3}{4 + 5 x}

x < - \frac{4}{5} or x > - \frac{4}{5}

Interval Notation

(- \infty, - \frac{4}{5}) \cup (- \frac{4}{5}, \infty)

Solution steps

Find undefined (singularity) points:

x = - \frac{4}{5}

The function domain

x < - \frac{4}{5} or x > - \frac{4}{5}

m = - 2, (2, - 4)

f (x) = 6 x^{4} + 16 x^{3}

3 x + 2 y = 12

0.00225 x^{2} + 5999.9325 x + 0.50625

f (x) = 8 x + 3

What is the domain of (x-3)/(4+5x) ?
The domain of (x-3)/(4+5x) is x<-4/5 \lor x>-4/5
