Function for the statement which suggest that the value of output is 4 less then value of input is,
[tex]y=x-4[/tex]
The completed table is,
Input (x) 1 2 3 4
Output (y) -3 -2 -1 0
What is function rule?
Function rule is the rule of writing the relationship between the two variables, one is dependent and another is independent.
It is given that, the output is 4 less than the input.
The table given in the problem is,
Input (x) 1 2 3 4
Output (y)
Here the output of the function is variable y, and the input of the function is x.
Thus we have to write such a function, which gives the value of (y) is 4 less then the value of (x), when we put this into the function.
y=x-4
Complete the table using the above function rule-
At (x) equal to 1,
y=(1)-4
y=-3
At (x) equal to 2,
y=(2)-4
y=-2
At (x) equal to 3,
y=(3)-4
y=-1
At (x) equal to 4,
y=(4)-4
y=0
Thus the completed table is,
Input (x) 1 2 3 4
Output (y) -3 -2 -1 0
Hence, the function rule for the statement, "the output is 4 less than the input is y=x-4 and completed table is,
Input (x) 1 2 3 4
Output (y) -3 -2 -1 0
