domain of f(x)=((1-5x)/(3+x))

domain

f (x) = (\frac{1 - 5 x}{3 + x})

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

\frac{- 5 x + 20}{x ^{2} - 16}

y + 2 x = 5

f (x) = 2 x^{3} + 12

f (x) = 3 cos (2 x)

f (x) = 35 x^{2} + 165 x

What is the domain of f(x)=((1-5x)/(3+x)) ?
The domain of f(x)=((1-5x)/(3+x)) is x<-3\lor x>-3
