domain of f(x)=(2x^2)/(x^2+2x-35)

domain

f (x) = \frac{2 x ^{2}}{x ^{2} + 2 x - 35}

x < - 7 or - 7 < x < 5 or x > 5

Interval Notation

(- \infty, - 7) \cup (- 7, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = - 7

The function domain

x < - 7 or - 7 < x < 5 or x > 5

y = \frac{x}{1 - x}

f (x) = - x^{2} + 2 x

x + 2 + 3

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

\frac{x + 3}{2}

What is the domain of f(x)=(2x^2)/(x^2+2x-35) ?
The domain of f(x)=(2x^2)/(x^2+2x-35) is x<-7\lor-7<x<5\lor x>5
