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

domain

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

x < 0 or x > 0

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

f (x) = \frac{2 - x}{x ^{2} - 6 x + 8}

8 csc (\frac{π}{4} x - \frac{3 π}{2})

y - 1 = - 5 (x + 1)

f (x) = 3 - 3 (x - 4)

f (x) = x^{4} - 2 x^{3} + x^{2} + 12 x + 8

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