Question

If the function rule is to add 6, and an output value is 6, what is the input value?

Answer 1

the function rule is to add 6, so:

y = x + 6 (y is the output, x is the input)

Since they gave you an output value of 6, you can plug it into the equation

y = x + 6 Plug in 6 for y

6 = x + 6 Subtract 6 on both sides to find the input value

0 = x

Answer 2

The answer is 0! The input value would be 0!
