Question

Sketch a graph of y =x-1/x+2 . State the position of any intercepts and asymptotes.

Answer 1

find y intercepts set x = 0; find x intercepts set y = 0
asymptotes is when the function is undefined meaning denominator is 0 so x = -2

Answer 2

x = -2 and 1?

Answer 3

when x =1 the function is 0. but when x = -2 the function is undefined.

Answer 4

Is the question (x-1)/(x+2) or x-(1/x)+2?
