For what value(s) of k will the relation not be a function r={(k-8.3+2.4k,-)/(4)k,4)} s = {(2−|k+1| , 4), (−6, 7)} i will rate and put brainilest answer

We are given two relations

(a)

Relation (R)

We know that

any relation can not be function when their inputs are same

so, we can set both x-values equal

and then we can solve for k

............Answer

(b)

S = {(2−|k+1| , 4), (−6, 7)}

We know that

any relation can not be function when their inputs are same

so, we can set both x-values equal

and then we can solve for k

Since, this is absolute function

so, we can break it into two parts

we get

so,

...............Answer
