Closing the gap between graphs

Question

I want to raise the lower graph g(x) toward the upper graph f(x) to make the points of the lower graph as close as possible to those of the upper graph, in other words, to make the graphs "match" as closely as possible.

I figured out how to do this by applying

However, after computing using the formula above, I get a value that I have to add to the function to shift the graph. Instead, I want a percentage I can multiply to each y-value of the points of g(x) to raise the graph.

How can I obtain this percentage?

Thanks!

Answer 1

for sure you are adding a value, a constant to the g(x) curve from x= a to b

since in general g(x₁)≠g(x₂)

adding a constant to each will not have a common percentage increase.

in general, cannot be made into a percentage with formula being used.

Answer 2

Divide f by g then multiply that by g ...
