The amount of stretch of a hanging spring versus the mass attached to the bottom of the spring was measured for different masses. The results are show mass (grams) 24 8 10
stretch (centimeters) 4 8 16 20
What is the constant of proportionality between the mass and the amount of stretch?

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
