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

f (x) = x^{3} + 2 x + 5

y = \frac{2 x + 1}{x ^{2} + x - 2}

f (x) = \frac{5}{- x + 2}

f (x) = 2 x - 5

\frac{y + 8}{y ^{2} - 3 y + 2}
