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

domain

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

x < - 4 or - 4 < x < 9 or x > 9

Interval Notation

(- \infty, - 4) \cup (- 4, 9) \cup (9, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4, x = 9

The function domain

x < - 4 or - 4 < x < 9 or x > 9

f (x) = csc (\frac{2 π}{7}) x - 2

f (x) = 2 x^{e}

f (x) = \frac{5}{( x + 1 )}

f (x) = 3^{\frac{x + 1}{x - 2}}

f (x) = x \cdot ∣ x ∣

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