domain of f(x)=28x^3+(12)/x

domain

f (x) = 28 x^{3} + \frac{12}{x}

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) = - 3 x^{2} + 30 x - 8

f (x) = x^{2} - 64

x - 5^{2}

y = 9 - x^{2}

What is the domain of f(x)=28x^3+(12)/x ?
The domain of f(x)=28x^3+(12)/x is x<0\lor x>0
