Xy=-36
x+y=-3
x= -36/y
-36/y + y = -3
-36 + y^2 = -3y
y^2 +3y -36 = 0
I think you have to use quadratic formula to find the 2 values of y and then plug in for x

Answer:
f(-1) = -8
f(1) = -12
Step-by-step explanation:
-1 and 1 are inputs to the function f which is shown on the graph.
The inputs are on the x-axis so when x = -1, the graph shows that the function f at -1 is approximately -8.
When x = 1, the function f is approximately -12.
