Missing details

Which type of function model would be appropriate for this situation?

Answer:

Linear function

Step-by-step explanation:

Given

[tex]y = 0.50x +9.75[/tex]

Required

The function model

A function of the form:

[tex]y = mx + b[/tex]

is referred to as a linear function where

[tex]m = slope/rate[/tex]

[tex]b=y\ intercept[/tex]

By comparison:

[tex]m = 0.50\ b = 9.75[/tex]

So, it is a linear function (linear model)
