domain of f(x)=ln(x^2-3x+2)

domain

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

x < 1 or x > 2

Interval Notation

(- \infty, 1) \cup (2, \infty)

Solution steps

Find positive values for logs:

x < 1 or x > 2

The function domain

x < 1 or x > 2

f (x) = x + 5 + 2

f (x) = x + 5 + 4

f (x) = 3 x - 12

f (x) = 8 x^{\frac{1}{3}}

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

What is the domain of f(x)=ln(x^2-3x+2) ?
The domain of f(x)=ln(x^2-3x+2) is x<1\lor x>2
