400Consider the table for a function.

 

Input, x 22 21 n 1 2 3

Output, y3 4 4 6 5 10

For what value of n would this table represent x as a function of y?

500The function y = x2 + 1 has the following table associated with it.

  Input, x –2 –1 0 1 2 3

Output, y 5 2 1 2 5 10

 

Suppose the function is reversed, making y the input and x the output. You would have to remove some of the values of y from the table in order to have x be a function of y. What would be the minimum number of y-values you would have to remove from the table in order to have x be a function of y? What y-values would you have to remove from the table?
