domain of f(x)=(2x)/(2^2+7x-4)

domain

f (x) = \frac{2 x}{2 ^{2} + 7 x - 4}

x < 0 or x > 0

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

f (x) = x^{3} + 3 x^{2} - x - 3

∣ x - 3 ∣ ∣ x - 2 ∣

f (x) = 5 x^{2} + 25

- 9 - x

f (x) = x (x + 2) (x - 2)

What is the domain of f(x)=(2x)/(2^2+7x-4) ?
The domain of f(x)=(2x)/(2^2+7x-4) is x<0\lor x>0
