Build a function from context by determining an explicit formula, recursive rule, or calculation process.
Define a function from an ordered calculation process
Problem
Start with input \(x\), multiply by \(3\), then add \(7\). Write the function rule for this process.
Big Picture
What this problem is really about
An ordered calculation process becomes a function by tracking the intermediate result after each instruction. We’ll begin with the input, apply the multiplication first, and then add to that completed product. A sample input can be run through both the verbal process and the symbolic rule to catch reversed operations or incorrect grouping.
