The graph shows two functions, f(x) and g(x). So point (-2,2) is on h(x)
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
In the question, we have two functions f(x)=x²-2 and g(x)=x²+2 by adding the function we will get the combined function.
So the graph i attached is showing the two functions and their relation to each other.
So we can see from the graph that the function is varying from the coordinates (-2,2)
Hence graph shows two functions, f(x) and g(x). So point (-2,2) is on h(x)
