domain of f(x)=sqrt((x+1)/(x^2-3x+2))

domain

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

- 1 \leq x < 1 or x > 2

Interval Notation

Solution steps

Find non-negative values for radicals:

- 1 \leq x < 1 or x > 2

Find undefined (singularity) points:

x = 2, x = 1

Combine real regions and undefined points for final function domain

- 1 \leq x < 1 or x > 2

7 x + 3 y = 9

1

3 x - 4

21 x + 7 y = 14

Y (x) = - \frac{1}{5} x - 6, (- 5, 3)

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