## anonymous one year ago How can you determine whether a relation is a function?

• This Question is Open
1. Nnesha

if x values repeats then relation isn't a function

2. Nnesha

for graph draw a vertical line if the graph of the equation intersect the vertical line at two points then relation isn't a function

3. Nnesha

$\rm (\color{ReD}{2},3)(4,5)(\color{ReD}{2},4)(9,3)$ example ^^ not a function x values r repeated which is 2

4. Nnesha

(x,y) first number represent x-coordinate 2nd one is y-coordinate (we don't care abt y-coordinate it's okay if y values are repeating in the relation )
