In squaring corners, you measure one side as 12 and the other side as 16. what's the length of the diagonal between these two side? a. 3 b. 20 c. 32 d. 8

The correct answer is D.

A function is a special relationship where each input has a single output.

It is often written as "f(x)" where x is the input value.

Example: f(x) = x/2 ("f of x equals x divided by 2")
It is a function because each input "x" has a single output "x/2":
• f(2) = 1
• f(16) = 8
• f(−10) = −5

So I guess she is right!
