Answer:
f(0)=g(0) is the only correct option.
Step-by-step explanation:
The value of the function is essentially the value of y in this graph. So it suffices to answer by checking and comparing the y values of both functions.
f(0)=g(0) must be correct as they are on the same point (and thus has the same y value)
f(-2)=4 but g(-2)=-4. So option b is wrong.
Option c is also wrong by checking the values.
