domain of sqrt(x^2-5x+6)

domain

x^{2} - 5 x + 6

x \leq 2 or x \geq 3

Interval Notation

(- \infty, 2] \cup [3, \infty)

Solution steps

Find non-negative values for radicals:

x \leq 2 or x \geq 3

The function domain

x \leq 2 or x \geq 3

\frac{2 x ^{2} - 4 x}{x ^{2} + 4 x + 4}

f (x) = \frac{x}{4 x - 1}

f (x) = 5 + 1 + x

5 - x + x^{2} - 4

f (x) = \frac{x ^{2} + 5 x - 3}{4 x - 1}

What is the domain of sqrt(x^2-5x+6) ?
The domain of sqrt(x^2-5x+6) is x<= 2\lor x>= 3
