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

domain

f (x) = (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

sec (2 x - 1)

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

f (x) = \frac{( x + 4 )}{x ^{2} - 9}

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

\frac{x ^{2}}{4 x - 3}

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