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

domain

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

x^{3} - 6 x^{2} - 36 x

x^{\frac{3}{2}} - 3 x^{\frac{5}{2}}

2 x^{2} + 32 x + 136

f (x) = \frac{x}{2}

f (x) = \frac{x}{7 - x}

What is the domain of f(x)=-x^2+4x-1 ?
