Question

A study is done of patients at a hospital that have a specific type of surgery to see the progression of their pain level on the day of the surgery. Below is the data showing the patient's self reported pain level (on a scale of 0 to 10) each hour after the surgery.

Answer 1

Which of the following types of functions have the potential to be a good model to fit the data and be used to predict the pain level of patients who have this surgery?
Potentially Good Model Not Potentially Good Model
A An exponential function with a growth factor greater than 1
B An exponential function with a growth factor between 0 and 1
C A linear function with a positive slope
D A linear function with a negative slope

Answer 12

i have no idea
doesn't look like exponential growth or decay, or a line of any sort
am i missing something in the question?

Answer 13

no, I posted everything from the question, to the graph, to the options

Answer 14

seems to go up and then go down, and not exponentially for either so maybe two linear functions

Answer 16

do you understand it?

Answer 17

@ganeshie8 ?

Answer 18

Potentially Good Model Not Potentially Good Model
A An exponential function with a growth factor greater than 1
B An exponential function with a growth factor between 0 and 1
C A linear function with a positive slope
D A linear function with a negative slope
E A quadratic function with a positive leading coefficient
F A quadratic function with a negative leading coefficient

Answer 19

im so sorry

Answer 20

oooh !!!

Answer 21

looks better, like a parabola open down

Answer 22

yeah lol

Answer 23

that would be a quadratic

Answer 24

with negative leading coefficient, which would make it open down

Answer 25

oh ok thank you :)

Answer 26

ye

Answer 27

ans is it a negative or positive slope?@satellite73 negative?
