domain of f(x)=x^2+(28)/x

domain

f (x) = x^{2} + \frac{28}{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) = (x - 8)^{2} \cdot (48 - x)

f (x) = \frac{- 5 x ^{2}}{( x - 9 ) ( x + 4 )}

y = \frac{4 x + 1}{2 x + 3} - \frac{3 x + 2}{5 x - 1}

\frac{( x ^{2} - 3 x + 2 )}{x ^{2} + x - 6}

\frac{( x - 3 ) ^{2}}{2}

What is the domain of f(x)=x^2+(28)/x ?
The domain of f(x)=x^2+(28)/x is x<0\lor x>0
