Graphs of the functions f and g are shown in the xy-plane. For which of the following values of x does f(x) + g(x) = 0?
1 answer:
Answer:
-2
Step-by-step explanation:
The functions of f(x) and g(x) are given
For f(x)+g(x)=0 , functions f and g should be in opposite sign
We can observe that at x=−2 , f(x)=2 and g(x)=−2
Therefore f(−2)+g(−2)=0
So the correct option is D (-2)
