Question

Jay's hair grows about 10 inches each year. Write a function that describes the length l in inches that Jay's hair will grow for each year k. Which kind of model best describes the function?

Answer 1

Answer: l= 10k

Linear model

Explanation:

Hi, to answer this question we have to write a function with the information given:

Since Jay's hair grows about 10 inches each year, the product of the inches per year that Jay's hair grows (10) and the number of years (k) must be equal to the total length of Jay’s hair after those years (l).

l= 10k

This is a linear model, where k is the independent variable (input) and y is the dependent variable (output).
