The function is assigning to <u>each element</u> of one set exactly <u>one element</u> from the other set.
First table represent a function.
Second table not represent a function (for -1 are four different numbers).
Third table represent a function.
Fourth table not represent a function (for -6 are two differen numbers 5 and 9)
Step-by-step explanation:
Answer:
$15,339
C(x) = 0.5x² − 100x + 20,339
Since this is a parabola, the minimum cost is at the vertex:
x = -b / (2a)
x = -(-100) / (2 × 0.5)
x = 100
So the minimum cost is:
C(100) = 0.5(100)² − 100(100) + 20,339
C(100) = 15,339
(1,3),(1,4),(1,5),(1,6),(2,3),(2,4),(2,5)
x+y<8. Let y=1, then x=(3, 4,5,6). If y=2, x=(3, 4,5).
