Answer:
A. Height is input, Weight is output
Step-by-step explanation:
We are given the statement,
"Weight is a function of height".
As we know,
In a function of the form [tex]y=f(x)[/tex], the input variable is 'x' and the output variable is 'y'.
If we write the given statement in the form [tex]y=f(x)[/tex], we get,
[tex]Weight=f(Height)[/tex]
This means that the input variable is 'Height' and the output variable is 'Weight'.
Hence, option A is correct.
