Question

Write a function rule for “The output is 5 less than the input.” Let x be the input and let y be the output. What is y?

Answer 1

`y=x-5`

Explanation:

Translate the statement from math to English. You said "output" means `y` and "input" means `x`, so the only other thing you need to know is "is" means `=` (equals):

`stackrely overbrace"The output" stackrel= overbrace"is" stackrel(x-5) overbrace"5 less than the input."`

Rewriting it yields:

`y=x-5`
