Which pair of functions are inverses of each other?

b. g(x) = (x+5) / 10

Step-by-step explanation:

f(x)=10x-5

y=10x-5

x'=10y'-5

10y'=x'+5

y' = (x'+5) / 10

g(x) = (x+5) / 10

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
