Hello there!

This parabola opens up because the leading coefficient is positive. In this case, the leading coefficient is 1.

If you want to find the leading coefficient, look at the term with the highest exponent. Look at the number behind it.

I really hope this helps!
Best wishes:)

Answer:

Step-by-step explanation:

Any parabola of the form y = ax^2+bx +c opens up or down depending on the sign of the leading coefficient a.

For the given parabola equation [tex]y=x^2-4[/tex]

a is 1 because x^2 can be seen as 1.x^2

Now since a=1 means it is positive means the parabola will opens upward .
