A set of input values is sometimes referred to as the replacement set for the independent variables. Evaluate each function for the given replacement set.
f(x)=3x6;{3.5,1,1/4,2,11}
f(x)=x(12x);{8,2/3,1,9,4}

It looks to me like they just want you to calculate a given function f(x) at set of x values. You will end up with a set of f(x) values. Then they want you do it again for a different set of independent valiables with a different
f(x)
For example, if f(x) = 3x 6 and x = 2, then f(x) = 0
If f(x) = x(12x) and x = 1, then f(x) = 1
In my opinion, someone is trying to make algebra more confusing than it really is, by talking about "replacement sets". Fads like this come and go.

i agree and drwls is right.and person is right they teach us and show is harder and confussing than is.

All of that complicated talk means:
Use each of those numbers for x
