domain of f(x)=x^4+x^2-1

domain

f (x) = x^{4} + x^{2} - 1

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

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

f (x) = x + 6 - 7

∣ x ∣ + ∣ x + 1 ∣ + ∣ 3 - x ∣

f (x) = 9995 \cdot 0.8 2^{0}

f (x) = 5 \cdot x^{2} + 81
