Question

The table shows values that represent a function.
x:-2/-3/6/7/5
Y:4/2/1/3/4
Part1: Write values that represent the inverse of the function represented in the table above.
x:
Y:
Part 2: Is the inverse a function? Explain your answer.
Remember that in a function, each input value can have only one output value.

Answer 1

May I help?

Answer 2

yes please @3mar

Answer 3

Thank you.

Answer 4

If we just plot these points on the grid, we will find if it represents a function or not.

Answer 5

so I have to graph it?

Answer 6

Not a condition, it is the simplest way, no more.
You can also examine the values of y corresponding to x ones, and search for any duplicate!

Answer 7

What you got?

Answer 8

2 and 3

Answer 9

2 and 3 ??

Answer 10

Is there any y-value corresponds to two or more x-values?

Search for any duplicate of x related to single y-value

Answer 12

Part 2: Is the inverse a function? Explain your answer.

To look for an inverse, reverse the values of x and y.

x 4/2/1/3/4

y -2/-3/6/7/5

Note that the x value of 4 is paired with -2.
The x value of 4 is also paired with 5

The inverse set is NOT a function because a single x of 4 is paired with two different y values for that x.
