domain of y=((2x+5))/((x-3))

domain

y = \frac{( 2 x + 5 )}{( x - 3 )}

x < 3 or x > 3

Interval Notation

(- \infty, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

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

g (x) = \frac{- 5 + 2 x}{5}

x^{2} - 2 x - 8

\frac{1}{2}

x - 2

What is the domain of y=((2x+5))/((x-3)) ?
The domain of y=((2x+5))/((x-3)) is x<3\lor x>3
