For problems like this, you have to determine which function applies by checking x against the limits of your function. In other words, is x greater than -1, or is x less than -1(I'm assuming that's what you meant or else your function is undefined between (x=-1) and (x=1)).
When x=-3/4, x >-1, so
When x=-4, x <-1, so
