Which function represents g(x), a reflection of f(x) = 6(one-third) Superscript x across the y-axis?

g(x) = −6(one-third) Superscript x
g(x) = −6(one-third) Superscript negative x
g(x) = 6(3)x
g(x) = 6(3)−x

a 90 degree rotation across the the origin followed by a reflection across the x-axis.

step-by-step explanation:

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
