@amistre64 {y|y = x^2 − 1, x is in integers}

amistre64 · Answer

does y=x^2 - 1 form a line, a quadratic, a cubic, is it a sine function?  what type of graph do you think we are dealing with?

anonymous · Answer

I have no idea ... so sorry

amistre64 · Answer

well, then the next best thing to do is to simply make a table of values to work with ....

amistre64 · Answer

you are being asked what the 4 smallest values of y are; given the rule that y=x^2-1

make a table of points to determine how y behaves since youre not able to determine a minimum from recognizing its structure.
