The number of grams, f, of dietary fiber recommended daily for children depends on the age, a, of the child, as shown in the following table. Find an equation for f in terms of a.

Question

The table looks like this (not sure how it will show up)

Column on left: Column on right:
Age of child, a Grams of Dietary Fiber
(in years) Recommended Daily, f
3 8
4 9
5 10
6 11
7 12
8 13

I need an equation in terms of dietary fiber, so I know it's going to be f = but from there I don't know what??

Thank you

Answer 1

f = a + 5

Answer 2

could you explain how you got the + 5 please?

Answer 3

he age numbers are all five less than the corresponding fiber numbers
