Which represents a function?

Mathematics

Answer:

Only the given table represents a function. Option 1 is correct.

Step-by-step explanation:

A relation is called a function, if there exist a unique value of y for each value of x. It means for each input there exist a unique output.

A function is always a relation but all relations are not function.

In the given table for each value of x, we have unique value of y, therefore the given table represents a function.

In second relation, at x=-2, the values of y are y=10 and y=-7. For single x, there are more than one value of y, therefore the second relation is not a function.

In third relation, at x=6,  the values of y are y=-2 and y=1. For single x, there are more than one value of y, therefore the third relation is not a function.

Please help look at the picture

Answer:

y = - 5x - 1

Step-by-step explanation:

The first thing to do (always) is pay attention to x =0. That at least gives you a partial answer. y = y' - 1. when you put 0 in for whatever y' is you get 0. What about the other numbers? How did they come about.

We have another clue. Whenever you put in a positive number for x, you get a negative answer for y. That's interesting. So y' has a minus sign associated with it.

y = -ax - 1    Make a>0 so there is only 1 minus sign. x cannot have an even power, because an even power would make everything positive except the -1.  

So we'll start with y= - ax - 1 We'll also make the assumption that a = 1

y = - x - 1 That won't work. a >1 otherwise x = 2 won't give - 11

y = -ax - 1

let x = 2

let y = - 11 Solve for a

y = - ax - 1

- 11 = -a*-2 - 1       add   1  to both sides

-11 + 1 = - a(-2) - 1 + 1

- 10 = -2a             Divide by - 2

- 10/-2 = -2a/-2

a = 5

Answer: y = - 5x - 1

In Ryan coorporation the first shift produced 5 1/2 times as many lightbulbs as the second shift. if the total lightul.bs produc
dimaraw [331]

Answer:

  • first shift: 13,750 bulbs
  • second shift: 2500 bulbs

Step-by-step explanation:

The production ratio is ...

  shift 1 : shift 2 = 5.5 : 1 = 11 : 2

so, the production on shift 1 as a ratio to the total is ...

  shift 1 : total = 11 : (11+2) = 11 : 13

The first shift produced ...

  (11/13)(16,250 bulbs) = 13,750 bulbs . . . . first shift

and the second shift produced ...

  (2/13)(16,250 bulbs) = 2,500 bulbs . . . . second shift

_____

Of course, once you have one of the numbers, you can also find the other by using the 5.5 factor or by subtracting from total production.
