domain of f(x)=((2x+4))/(x-9)

domain

f (x) = \frac{( 2 x + 4 )}{x - 9}

x < 9 or x > 9

Interval Notation

(- \infty, 9) \cup (9, \infty)

Solution steps

Find undefined (singularity) points:

x = 9

The function domain

x < 9 or x > 9

in v erse f (x) = - x^{2} + 2

p a r i t y y = \frac{8 x}{3 - tan ( x )}

d o main f (x) = 1 - x

d o main f (x) = \frac{( x ^{2} + 1 )}{( x + 3 )}

in v erse x^{2} - 6 x

What is the domain of f(x)=((2x+4))/(x-9) ?
The domain of f(x)=((2x+4))/(x-9) is x<9\lor x>9
