graft in the co ordinate plane problem is a function

in problem Bee is not of functions Remember nata functions

there's got to be a hole in or something undefined

What is the maximum number of points of intersection that

the two parappa lives could have Well all right let's

think about this We're going to draw them and it's

going to look something like this Art will probably a

is a function so it opens either downwards or upwards

like that Problem b isn't cool enough to be in

the function club which means that it's oriented horizontally opening

either to the left or the right that is a

vertical line could pass through it in two places So

they're like there and there And if we look at

our sketch here of the horizontal and vertical ones we

find the greatest possible number of intersection points is four

so they'd be one two three And yet for so 00:01:12.763 --> [endTime] that's it answer is b for
