Answer:
g(x) = (x + 3)^2
Step-by-step explanation:
When a function is shifted to the left or right we can think of a change of units, like a new independent variable is used.
If we have a quadratic function 

and the graph is shifted 3 units to the left, then we can think of a new unit u that is:

The vertix of this parabola, that happens for u=0, happens for x=-3, as the graph is shifted 3 units to the left.
Then, the relation between u and x is:

We can use this relation in the new graph and replace u as:

All you gotta do is plug in the points and see if the answer you get is less than or equal to 12. if it is then yes. if it's higher than 12 no. one of your points is (-2,1) which gives you -4 + (-4) than is less than 12 so you put yes and so on
