Best ResponseYou've already chosen the best response.0So you go down the table and make the equation y= x^2

Best ResponseYou've already chosen the best response.1good work, can you polt the rest of the points?

Best ResponseYou've already chosen the best response.1very good, now if we connect these points, then the line will be y=x^2

Best ResponseYou've already chosen the best response.1but the question is y>x^2

Best ResponseYou've already chosen the best response.0but where would we shade

Best ResponseYou've already chosen the best response.1well if y is greater then x^2, the y values in the the shaded region must be of greater values than the y=x^2 curve

Best ResponseYou've already chosen the best response.1so shade the region above the curve

Best ResponseYou've already chosen the best response.0Okay thanks, I think I have it now!!

Best ResponseYou've already chosen the best response.1some times it is good to choose a point and check it , say the point (0,1) which is above the curve, to check y>x^2 1>0^2 1>0 which is true, so the point is in the region

Best ResponseYou've already chosen the best response.0ok thanks for clarifying that, I will use this method on the other questions!!

Best ResponseYou've already chosen the best response.1the last thing to mention is that the line in not included in the region because we are doing y>x^2 if we were doing y≥x^2, the line would be included

Best ResponseYou've already chosen the best response.0Because of the greater than or equal sign????

Best ResponseYou've already chosen the best response.1so maybe draw a dashed line like this dw:1350918432085:dw

Best ResponseYou've already chosen the best response.0okay is it possible to shade in more than one place?

Best ResponseYou've already chosen the best response.1but you would need a complicated equation
