Answer:
A.
Step-by-step explanation:
Anwer A has the following equation:

In this equation, we can calculated the intercept replacing x by 0, as:

if this is the answer, the graph of g(x) should be through the point (0,-3) and that happens.
Additionally, the roots of the equations are calculated replacing g(x) by 0 and solving for x, so:

It means that the graph of g(x) should be through the points (2.236,0) and (-2.236,0) and that happens too.
So, the answer is A,
