F-BF.1.a Warmup M1-015-A15-V04

Build a function from context by determining an explicit formula, recursive rule, or calculation process.

Critique and correct a proposed function model

Problem

The proposed model \(P(n)~=~3~+~50n\) is meant to represent an initial height of \(50~\text{cm}\) plus \(3~\text{cm}~\text{per}~\text{week}\). Correct the model and identify the error.

Answer choices

corrected model = P(n)=53n; error type = combine parameters

corrected model = P(n)=3+50n; error type = no error

corrected model = P(n)=50n+3; error type = initial height is 50

corrected model = P(n)=50+3n; error type = swapped initial value and rate
