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^{2} - 4 x + 5

f (x) = \frac{2 x + 3}{3 x - 1}

f (x) = x^{2} - 2 x - 9

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

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