The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Up

Step-by-step explanation:

Here the easy rules to remember the orientation of the parabolas are

a) If x is squared it opens up or down. And its coefficient of {

Hence in our equation of parabola

x is squared and its coefficient is positive , hence it opens up towards positive y axis.

b) well because you get well

yess
