domain of f(x)=-x^2+4x+5

domain

f (x) = - x^{2} + 4 x + 5

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

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

f (x) = - 10 x + 8

y = x - \frac{1}{x}

y = \frac{5 x}{5 + 9 x}
