Please help :[ write an equation that represents the transformations formed by the following items:

a) horizontally shifting the graph 4 units to the left of f(x)=√x and then vertically compression by a factor of 1/3

b) vertically stretching the graph by a factor of 4 of f(x)=√x and then vertically shifting the graph 3 units up

c) horizontally stretching the graph of f(x)=√x by a factor of 2 and then vertically shifting the graph 6 units down

Abusiness plan is centered around a circular area of distribution. the plan calls for the radius of the distribution to increase 50 miles per year. the investors have asked that the plan include a reference to the area of distribution based on the number of years in business. these functions model this plan: radius in y years: r(y) = 50y total area: a(r) = πr2; r in miles what is a(r( the total area in y years? a(r(y)) = 50πy2 a(r(y)) = 2,500πy2 a(r(y)) = 50πr2 a(r(y)) = 2,500πr2
