What kind of relation is this? One to one? One to many? Or Many to one? F={(2,1),(4,2),(8,4),(10,5)} G={(-2,4),(-1,1),(0,0),(3,9)}
if we consider both ,then its many to one function as for different input values ,yu are getting the same output as (-2,4) and (8,4) ..
How do you know if an equation is one to one, many to one or one to many?
The value you get after giving an input , if that output cant be obtained for any other different input value and also if for same input value ,yu dont get multiple different output values ,then its one to one function....other three variations of the above mentioned two conditions will result in many to one ,one to many and many to many type functions
|dw:1382261816782:dw| is this a function? or a mere relation?
the vertical dots indicated that for one value of x there are 2 values of y so this is a one-to-many relation and not a function
this is many to many relation...as yu forgot to consider the horizontal dots @cwrw238
function is a "well-behaved" relation..This means that, while all functions are relations, since they pair information, not all relations are functions. Functions are a sub-classification of relations @Pandaaa
how about this?|dw:1382262195177:dw| sorry. I really can't tell what is a mere relation and which is not.
i didnt really get this figure ?
It's just simple like that. no dots are indicated just lines.
ok...i tell the way... To see if the relation is a function then check if the X in all the coordinates are the same or different. If there are any similar numbers for the X then that relation is not a function. If there are no similar numbers for the X then that relation is a function.
you mean, if any numbers pass through the x coordinate is not a function?
i mean only many to one and one to one relations are functions
