domain of f(x)=x+1,x<-1

domain

f (x) = x + 1, x < - 1

x < - 1

Interval Notation

(- \infty, - 1)

Solution steps

Set the domain to the given interval

x < - 1

The function has no undefined points nor domain constraints. Therefore, the domain is

x < - 1

f (x) = \frac{4 x}{- 3 x + 11}

2 x^{2} - x + 4

f (x) = lo g_{10} (2 x - 1) - 1

f (x) = ln (x^{4} - 15)

Y (x) = \frac{x ^{2} + 3}{x ^{2} + x}
