can someone help me to make this a non- function.
f(x){(1,-8),(3,-4),(5,0),(9,4),(10,-2)
To make the given set of points a non-function, there should be at least one x-value from the given set that corresponds to multiple y-values. In this case, we can achieve that by repeating an x-value.
For example, we can repeat the x-value of 3 and assign two different y-values to it, such as (-4) and (-5). So, the modified set of points could be:
{(1,-8), (3,-4), (3,-5), (5,0), (9,4), (10,-2)}
Now, this set of points is not a function because the x-value of 3 has two different y-values associated with it.
