Which relation is a function? a. {(2, 3), (1, 5), (2,7)} b. {(-1,5), (-2,6), (-3,7)} c. {(11,9), (11,5), (9,3)} d. {(3,8), (0,8), (3,-2)} i will mark you brainliest

B. {(-1,5), (-2,6), (-3,7)}

Step-by-step explanation:

Every element in the x value is related to some element in y value.

But the x value would not function if it has two or more y values.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

2,600 divided by 80 = 32.5
