Is Is the following relation a function A. Yes B. no

YES

Step-by-step explanation:

To determine a function on a graph use the vertical line test!

put a vertical line through the graph at ANY POINT and if it only passes through one point then it is a function.

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

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.
