f(x)=(x^2-1/(x^2))(x^2+1/(x^2))

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

Domain : x < 0 or x > 0

Range : - \infty < f (x) < \infty

X Intercepts : (1, 0), (- 1, 0)

Asymptotes : Vertical x = 0

Extreme Points : None

Solution steps

Domain of

(x^{2} - \frac{1}{x ^{2}}) (x^{2} + \frac{1}{x ^{2}}) : x < 0 or x > 0

Range of

(x^{2} - \frac{1}{x ^{2}}) (x^{2} + \frac{1}{x ^{2}}) : - \infty < f (x) < \infty

Axis interception points of

(x^{2} - \frac{1}{x ^{2}}) (x^{2} + \frac{1}{x ^{2}}) :

X Intercepts

: (1, 0), (- 1, 0)

Asymptotes of

(x^{2} - \frac{1}{x ^{2}}) (x^{2} + \frac{1}{x ^{2}}) :

Vertical

: x = 0

Extreme Points of

(x^{2} - \frac{1}{x ^{2}}) (x^{2} + \frac{1}{x ^{2}}) :

None

y = \frac{3 x}{2 x ^{2}}

y = 1 + x + 1 - x

y = 4 x^{- 3} + 4 x

f (x) = 14 x^{4}

y = tan (\frac{x}{4})
