f(x)=3x-6;{-3.5,-1,1/4,2,11}

f(x)=x(1-2x);{-8,2/3,1,9,4}

**drwls**, Sunday, January 4, 2009 at 12:19amIt 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(1-2x) 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.

**Kate**, Sunday, January 4, 2009 at 12:41amA 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)=3x-6;{-3.5,-1,1/4,2,11}
