domain of f(x)=(45x^2)/(25x)

domain

f (x) = \frac{45 x ^{2}}{25 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

3 cos^{2} (x)

f (x) = \frac{5}{4} x - 10

\frac{64}{x ^{2}} + 81

y = - 4 x

\frac{- x ^{2} + 4 x - 4}{x ^{3} - 3 x ^{2} - 9 x + 27}

What is the domain of f(x)=(45x^2)/(25x) ?
The domain of f(x)=(45x^2)/(25x) is x<0\lor x>0
