domain of f(x)= 3/(y+1)-4

domain

f (x) = \frac{3}{y + 1} - 4

y < - 1 or y > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

y = - 1

The function domain

y < - 1 or y > - 1

\frac{e ^{x} - e ^{- x}}{2}

f (x) = - 7 x - 1

2 x + 3 y = - 9

y = 2 (x + 1)^{2} - 3

f (x) = - x^{2} - 4 x - 1

What is the domain of f(x)= 3/(y+1)-4 ?
The domain of f(x)= 3/(y+1)-4 is y<-1\lor y>-1
