Question 82486This question is from textbook
: I need to match the function has with its possible range.
function is y=-5x + 1
ranges to choose from:
-7,-4,-1,2,5,8
-5,-3,-1,1,3
11,6,1,-4,-9,-14
4,3,2,1,0
I have no idea how to even begin to solve this question. Can you tell me the range and explain how it is done. This is from a worksheet from McDougal Littell Middle School Math, Course 2 Chapter 7.

You can put this solution on YOUR website! need to match the function has with its possible range.
function is y=-5x + 1
------------------
Comment: The function has a slope of -5 which means "as x increases
one, y decreases 5". So you should look for a sequence where the
numbers are decreasing 5 at each step.
----------------
ranges to choose from:
-7,-4,-1,2,5,8
-5,-3,-1,1,3
11,6,1,-4,-9,-14
4,3,2,1,0
--------
The sequence 11,6,1,-4,-9,-14 satisfies that requirement.
