Question

Much appreciated!

Answer 1

OK, you're basically trying to find out what the function is. Do you see a pattern in the values?

Answer 2

OK, so can you write that as a function:

y=f(x)?

Answer 3

So when you input 0 you get 1, you input 1 you get 2.

You already said that you just take the input + 1 to get the output. Can you write that as a function?

Answer 4

A function is just a relationship between x (input) and y (output). We worked with a function in your last question too. It was y=2x+2.

Answer 5

So you said this:

Output = Input + 1

Answer 6

The output is y and the input is x.

Output = Input + 1

y = x + 1

Answer 7

Well for any of the numbers you have (0, 1, 2, 4), you can plug one of those numbers in (as x) into the equation y=x+1 and you'll get the output (1,2,3,5).

Answer 8

You were right from the very beginning, you just needed help converting it from words to an equation!
