What is the graph of the function = f of x equals negative x squared minus 9 x minus 20 all over x plus 4 ?

See below

Step-by-step explanation:

Lets do the long division:-

            - x - 5

x + 4 ( -x^2 - 9x - 20

         -x^2 - 4x     Subtract:-

                  -5x - 20

                  -5x - 20

The quotent is -x - 5 with no remainder so the graph will be a straight line with negative slope of  -1, and y-intercept at (0, -5).

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
