domain of f(x)=(-5x^2)/((x-4)(x+3))

domain

f (x) = \frac{- 5 x ^{2}}{( x - 4 ) ( x + 3 )}

x < - 3 or - 3 < x < 4 or x > 4

Interval Notation

(- \infty, - 3) \cup (- 3, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = - 3

The function domain

x < - 3 or - 3 < x < 4 or x > 4

\frac{2 x - 3}{4}

x^{5}

y = - x + 2

x + 3 y = - 9

x - 6 y - 7

What is the domain of f(x)=(-5x^2)/((x-4)(x+3)) ?
The domain of f(x)=(-5x^2)/((x-4)(x+3)) is x<-3\lor-3<x<4\lor x>4
