the first two points pass the third no as 5 squared cannot equal -25!

You can check for yourself by substituting the corresponding coordinates into the function. Answer: c doesn't fit the rest do

come on! it's easy! you substitute the first number for x and the second for y Example: point a 5;25 y=x squared we substitute 25=5 squared i.e. 25=25 answer: point a 5;25 belongs y=x squared point b -5;25 belongs as -5 squared=25 and so 25=25 point c 5;-25 does not belong as 5 squared=25 and 25 does not equal -25
