Use the domain and range of each of the following relations to determine which is a function
a {(7,5), (-6, 0), (2, 3)
b. {(7,5), (-6,0), (-6, - 2), (2,3)}
c. {7. - 6, 2, - 7
d {(7,5). (-6, 0), (7,3)}

250

step-by-step explanation:

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.

(23*2)-12=x     x=34
