You can put this solution on YOUR website!
i'm not exactly sure what you are looking for.

your equation is y = (x^2 + x - 2) / (x - 1)

when x = 1, the function is undefined because you can't divide by 0 and get a real number.

therefore, the function is good for all values of x except when x = 1.

there is not an asymptote to this equation because the denominator cancels out when you factor the numerator.

if you factor (x^2 + x - 2), you get (x + 2) * (x - 1).

the equation bec0omes y = (x + 2) * (x - 1) / (x - 1).

the (x - 1) in the numerator and the denominator cancel out and you are left with y = x + 2.

when you graph the equation, that's what you see.

here's the graph.

$$$

as you can see, the value of the function is undefined when x = 1.
for all other values of x, the function is valid.

now to your statements that i don't completely understand what you mean by them.

x - 1 = 0, x = 1
Undefined: x ≠ 1, x < 1, x > 1

the function is defined when x is not equal to 1.
if the statement is saying that the function is undefined when x is not equal to 1, then the statement is false.
