Question

Suppose an investment of $8,400 doubles in value every decade. The function f(x) = 8400∙2x gives the value of the investment after x decades. How much is the investment worth after 3 decades? Group of answer choices $50,400 $504,000 $67,200 $168,000

Answer 1

50400

Step-by-step explanation:You just need to plug it in 3 where x is.Once you done that you need to multiply 8400x2 because we multiply from left to right this will equal 16800 then finally multiply that by 3 and you get 50400 or you could multiply first 2x3 and get 6 then 8400x6 which still equals the same thing.
