Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.
(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.
Part B: All we have to do is plug in 11 for x in the function given to find the answer:

In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.
Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:
Answer:
first one: 3 1/3 = 7/3 second: 2 3/4 = 11/4
third one: 3 1/3 + 2 3/4 = 10/3 + 11/4 = 40/12 + 44/12
there fore the answer is: 84/12 or 7
this may help you the first one question only.
Answer:
Hi .. im happy to help
answer is 0.033
Step-by-step explanation:
P = C(4,4)÷C(10,4)
P = 1 ÷ 30

p = 0.033

In the given question , we have a function given , which is

And we need to find the value of y when x=5.
So we substitute 5 for x and solve for y, that is

And on rounding to the nearest tenths, we will get

So when x=5, y=0.4
