What is the graph of the function f(x)= f(x)=-x^2-9x-20/x+4?

Synthetic division? You’ll make the positive 4 a negative then set it up as a long division except you only put the numbers and not the x’s. So it would be -4 division sign then on the right of the line is -1 -9-20. Then you bring the -1 down and multiply -4 by -1 which would be 4 and you put it under -9 then do the simple math for those then bring the -5 down to the right of the negative 1. Then multiply negative 4 by negative 5 which is positive 20. So your answer wouldn’t have a remainder. So it would be -x-5
