I don’t see anything. What is the problem.
F(x) = (-x²+x+20) / (x+4)
-x²+x+20 | x+4
+x²+4x -x+5
\\\\ 5x+20
-5x-20
\\\\\\\\\
f(x) = (x+4)(-x+5) / (x+4)
f(x) = (-x+5)
The graph is a decreasing line, with origin from 5.
You have to do whatever is in the parentheses first which gets you:
4-(-2)
Two negatives equal one positive so it would be:
4+2
And 4 plus 2 is of course 6.
