According to the program operation in the figure: when the input data is 4, the output data is 4______ ．

According to the program operation in the figure: when the input data is 4, the output data is 4______ ．

According to the meaning of the question, (4-6) / (- 2) = 1 < 2, so substitute 1 into the calculation: (1-6) / (- 2) = 2.5 > 2, that is, 2.5 is the final result

As shown in the figure below is a numerical calculation program (input a numerical value, complete a box Neide operation, input the result into the next box to continue calculation)
Input x → + 4 → - (- 3) → - 5 → > 2 - (yes) input
1. Suppose "input X" is - 1, then what is "input"?
2. Suppose "input X" is - 2, then what is "input"?

1. Input is 3
2. The input is 4

Xiao Ming designed a computer program. The data of input number x and output number y are as follows:
Input number x 1 2 3 4 5
The output number y is half, two thirds, three quarters, four fifths and five sixths
Which method is used to express the functional relationship between X and y?

Y=1-1/(X+1)
It's an inverse scale function
