i have no idea how to do these can someone please help me !

Answer 1

Dont even know what your function is... :)

Answer 2

how do i add the table to this answer box? @Jhannybean

Answer 3

Answer 4

we need to know the function

if you have a table, then use the draw button...

Answer 5

Or if you want to go the extra mile, try it out with LaTeX:

`\begin{array}{c|c} `
`x values & f(x) values `
` 1 & f(1) `
` ... & ... `
`\end{array} `

Answer 6

help on the last questions!!!!!!!!!!!!! please !

Answer 7

Ok, for part (a) we deal with invertibility. In order for the inverse relation to be a function, every unique element in the domain of the inverse relation can only map to at most one element in the domain of the original function.

For this problem, this basically means that if you want f(t) to have an inverse function, then you have to fill in the blanks for f(t) with values that are NOT repeats of any of the other f(t) values.

Similarly, if you want g(t) not have an inverse, you fill in a blank with at least one repeat value. The repeat value could be 0 0.5 1.3 2 2.7 4 (the numbers that they provide for you) or you could also repeat the one of the numbers that you filled in the blank.

For example, I could fill in the blanks for f(t) with 6 5 and 10 .
And I could fill in the blanks for g(t) with by filling in the blanks with 0 5 and 6, or I could also fill them in with 7 7 7. Do you see how the (0,5,6,) repeats 0, and the (7,7,7) repeats 7?

Answer 8

You should probably ignore the first paragraph on my first post. It's too complicated for this level of math.

To demonstrate how a relation is a function, you'll want to use something called the "vertical line test"

By the way, vertical goes up and down. Horizontal lines go from side to side. Don't confuse the horizontal line test with the vertical line test. Horizontal is for checking something else. Vertical is for checking if your actually dealing with a function.

Answer 9

Ok, so part (c)... I kinda picked numbers that aren't fun to make a story with. You should pick better numbers. I gave you the rules for what kinds of numbers you can pick, so you should be able to pick better numbers and come up with two stories.

Answer 10

Part (d) depends on your story.
