domain of f(x)=(3x^2)/(x^2+2x-35)

domain

f (x) = \frac{3 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

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

f (x) = 2 x + 1 + 4

lo g_{10} (x + 8)

f (x) = 3 x^{5} + 5 x^{3}

What is the domain of f(x)=(3x^2)/(x^2+2x-35) ?
The domain of f(x)=(3x^2)/(x^2+2x-35) is x<-7\lor-7<x<5\lor x>5
