Work Step by Step
This question asks for the graph of $f(x) = x^2 + 1$ and $g(x) = 3- x^2$, and finally a graph that combines the two by adding $f(x)$ to $g(x)$.
So $f(x) + g(x)$ should lead to a graph of $4$
The purple graph displays f(x)
The black graph displays g(x)
The red graph displays f(x) + g(x)
