Answer both questions
1) which set is a function?
a) {(0,3), (3,0), (0,4), (4,0)}
b) {(0,2), (2,0), (4,6), (6,4)}
c) {(2,6), (3,6), (4,6), (2,0)}
d) {(6,2), (2,0), (4,6), (6,4)}

2)which set of ordered pairs does not represent a function?
a) (0, 1), (2, 2), (4, 8), (-2, 7), (5, 8)
b) (0, 1), (2, 2), (4, 8), (2, 7), (5, 8), (7, 9)
c) (-3, 6), (2, 7), (0, 5), (1, 5), (4, 9), (5, 4)
d) (-4, 2), (-3, 2), (-2, 2), (-1, 2), (0, 2), (1, 2)

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
