Answer:
[tex]Q(a) = w[/tex]
Step-by-step explanation:
Given
w = weight
a = age
Required
Represent the weight as a function of age
When writing a function.
[tex]y = f(x)[/tex]
means that y is a function of x
Using the above to answer the given question, we have:
[tex]w = Q(a)[/tex]
Which means w is a function of a
and can be rewritten as:
[tex]Q(a) = w[/tex]
