Answer:
Step-by-step explanation:
Disagree. (4, 4) and (4, 5) show that for a single input, 4, there are two distinct outputs (4 and 5). In a function no more than 1 output can be associated with a given input.
The given relation is not a function.
which expression is equivalent to 3 x - 3y
3 x - 3y
factor out the 3
3(x-y)
4
2x-2/5=4
2x= 4+(2/5)
2x= 4/5+20/5
x=(22/5)/2
x= 22/10 or 11/5
check:
2(11/5)-2/5=(22/5)-(2/5)
=20/5
=4
