Geometric mean is the nth root of the product of n numbers

For two numbers it's the square root

for three numbers it's the cube root

for 4 numbers it's the fourth root

etc.

5 and 20

m = √(5 * 20) =

m = √100

m = 10

3 and 12

m = √(3 * 12)

m = √36

m = 6

do the rest the same way

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
