I have y=(2x+4)/(x+1) i have been asked to make a table of variation for this function. I know that D=R\{-1}. But how do i find the places where the function changes direction? I want to find the value of x and what it gives us. Could someone please give me the answer with detailled intermediary steps?? Thanks
x=-3 , y=.. x=-2 , y = ... x=-3/2 , y = ... x=-1/2 , y =... x=0 , y = ... x=1 , =... x=2 , ..
