domain of f(x)=(56x+49)/(x^2)

domain

f (x) = \frac{56 x + 49}{x ^{2}}

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) = \frac{5}{5 x - 16}

f (y) = 4 x + 12

\frac{x ^{3} - 3 x ^{2} - 4 x}{x - 4}

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

f (x) = 4 x + 3

What is the domain of f(x)=(56x+49)/(x^2) ?
The domain of f(x)=(56x+49)/(x^2) is x<0\lor x>0
