Question

My son needs help with this question. Please help.
Write a function rule for each table.
x | f(x)
1 | 0.5
2 | 1
3 | 1.5
4 | 2

Any and all help is greatly appreciated since this is something that I am not familiar with.

Answer 1

It looks to me like f(x) is one-half of x. Write that as an algebraic term.

Answer 2

f(X)=1/2x
