Answer:
Third one
Step-by-step explanation:
To be a function x must only have 1 y value or you're really describing a limit which isn't part of the outputs
However, In your case two x values equaling the same y value is fine because the x values do not have two y values
This is a function, as each x value corresponds to one y value
My apologies I was confused with my first answer.
Answer:

Step-by-step explanation:
if you want it simplified it is 
I will draw a rough figure, you can draw it neatly.
Probability =
Probability = No. of favourable outcomes/ Total no. of outcomes
Probability = No. of favourable outcomes/ Total no. of outcomesTotal number of outcomes = 4
So, here:
P(2) = 2/4 = 1/2
P(1) = 1/4
P(3) = 1/4
P(4) = 0
Here, the probability of getting 2 is ½.
Probability of getting 1 is ¼.
Probability of getting 3 is ¼.
Probability of getting 4 is 0.
Answer:
66000
Step-by-step explanation:
since the graph represents a proprtional relationship the equation of the graph must be written this way :
y = ax where a is the slope
you can notice that 2 goes with 24000
so 24000 = 2a then x = 24000/2= 12000
so a = 12000
now replace x with 5.5
y= 5.5*12000=66000
