Answer:f(x) = 11 - xStep-by-step explanation:We have to find a function that has a graph as x + y = 11.
Now, the equation given is Β x + y = 11
β y = 11 - x
So, if we consider x as an independent variable and y as a dependent variable whose values are dependent on the values of x, then er can write y = f(x) = 11 - x
So, the function f(x) = 11 - x has the same graph as x + y = 11. (Answer)
