Find any points of discontinuity for the rational function.

y=x-2/ x^2-4x+3

To find points of discontinuity for a rational function, we need to find the values of x where the denominator becomes zero.

In this case, the denominator is x^2 - 4x + 3. We can find the points of discontinuity by setting the denominator equal to zero and solving for x:

x^2 - 4x + 3 = 0

This is a quadratic equation, which can be factored as:

(x - 3)(x - 1) = 0

Setting each factor equal to zero:

x - 3 = 0
x = 3

x - 1 = 0
x = 1

Therefore, the points of discontinuity for the rational function y = (x - 2)/(x^2 - 4x + 3) are x = 3 and x = 1.
