domain of (4x)/(x+3)

Solution

domain

\frac{4 x}{x + 3}

Solution

x < - 3 or x > - 3

+1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

\frac{x ^{2} + x - 6}{x - 1}

domain of f(x)=sqrt(x+7)+3 domain

f (x) = x + 7 + 3

range of f(x)=k(x)(x^{2+1})=x(x+6)+1 range

f (x) = k (x) (x^{2 + 1}) = x (x + 6) + 1

domain of f(x)=sqrt(2x-48)domain

f (x) = 2 x - 48
