domain of (x^2-36)/(5x-20)

domain

\frac{x ^{2} - 36}{5 x - 20}

x < 4 or x > 4

Interval Notation

(- \infty, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4

The function domain

x < 4 or x > 4

f (x) = \frac{x + 1}{x ^{2} + x - 6}

f (x) = t

8 x + 1

x^{2} + 3 y - 6 x + 9 = 0

arccos (cos (x))

What is the domain of (x^2-36)/(5x-20) ?
The domain of (x^2-36)/(5x-20) is x<4\lor x>4
