Question

Johnny has been planting blueberries in a garden in his backyard. Johnny started with blueberries in one square foot of garden modeled by the function s(x) = 10. He is allowed to convert more of the garden, and each additional square foot he maintains allows his blueberry plants to produce more by a rate of a(x) = 1.4x-2.

Answer 1

Do you need help ?

Answer 2

s(x) + s(x) * a(x) = Total production
^--- starting with this no matter what
increasing by a(x) factor on what he can produce at first so s(x) * a(x)

Answer 3

Let P(x) be the production function per square root for x>=1
P(x)=s(x)+s(x)*a(x)
= 10 + 10*(1.4x-2)

Answer 4

x is the number of square feet you want to maintain

Answer 5

so when it asks how much he will maintain for 5, that means he's maintaining 4 more square feet

Answer 6

10+10(1.4(4)-2)=Production
