Answer:

C

Step-by-step explanation:

Ok, so to do this, we are just going to plug in (0,0) and see it it checks out.

Let's take the first question. y[tex]y\geq x^{2} -4[/tex]

When we plug (0,0) into this, we get the following

[tex]0\leq 0^{2} -4[/tex]

[tex]0\leq 0-4[/tex]

[tex]0\leq -4[/tex]

This is false.

Let's check the other equation:

[tex]0>2(0)-1\\0>0-1\\0>-1[/tex]

This is true.

So the correct answer is C
