Question

for which value of x is x-2/x^2+3x+2 undefined?

Answer 1

You know how you can't divide by zero? Well, that's where the function is undefined.

Answer 2

Set the quadratic expression in the denominator equal to 0. Factor, and solve for x. The function won't be defined at those x values.

Answer 3

excluded values...
just set the denominator equal to zero and solve for x in the denominator only
in this case you are solving a quadratic equation for the x
