Step-by-step explanation:
[tex]y=-x^2[/tex]
Put any values of x and calculate a value of y.
[tex]x=0\to y=-0^2=0\to(0,\ 0)\\\\x=-1\to y=-(-1)^2=-1\to(-1,\ -1)\\\\x=1\to y=-1^2=-1\to(1,\ -1)\\\\x=-2\to y=-(-2)^2=-4\to(-2,\ 4)\\\\x=2\to y=-2^2=-4\to(2,\ 4)\\\\x=-3\to y=-(-3)^2=-9\to(-3,\ -9)\\\\x=3\to y=-3^2=-9\to(3,\ -9)[/tex]
