domain of f(x)=(7/x)+(1/(x^2))

domain

f (x) = (\frac{7}{x}) + (\frac{1}{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}{- x ^{2} - 3 x + 4}

(- 6, 6), (2, - 4)

y = x + 7

5 sin (2 x)

y = 2 x + 6

What is the domain of f(x)=(7/x)+(1/(x^2)) ?
The domain of f(x)=(7/x)+(1/(x^2)) is x<0\lor x>0
