suppose an investment of $2,300 doubles in value every decade. the function f(x)=2,300⋅2^x
gives the value of the investment after x decades. how much is the investment worth after 2 decades?
a ) 2,355,200
b ) 92,000
c ) 46,000
d ) 9,200
To find out how much the investment is worth after two decades, we substitute x = 2 into the function f(x) = 2,300 * 2^x:
f(2) = 2,300 * 2^2
f(2) = 2,300 * 4
f(2) = 9,200
Therefore, after two decades, the investment is worth $9,200.
So, the correct option is d) 9,200.
