Answer:
Look at the end behavior down.
there is:
1) up up (the parabola looking up)
2)down down (the parabola looking down)
3) down up (the positive cubic function)
4) up down (the negative cubic function)
*You have to memorize the conditions in the picture to answer any question*
g(x) = X^2
x^2 is a quadratic equation
it has even power and a positive leading coefficient so it is has a behavior of up-up
