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

domain

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

- \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

7 x - 21 + \frac{x}{x - 8}

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

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

3 x

f (x) = cos (\frac{1}{x})
