This is a function, as each input value (x) corresponds to a unique output value (y).
The pattern of the output values suggests that this is a nonlinear function. Specifically, the output values seem to be the result of raising the input values to the power of 3 (i.e., y = x^3).
To find the missing value, one should calculate 7^3, which is equal to 343. Thus, the missing value for y when x is 7 is 343.

is this Linear OR Nonlinear Function OR Not a Function

is it Linear OR Nonlinear
Apologies for the confusion. This is a nonlinear function. In a linear function, the output values would change by a constant rate with each increase in the input values. However, in this case, the output values are the cube of the input values, indicating a nonlinear relationship.
