Suppose an investment of $2,300 doubles in value every decade. the function gives the value of the investment after x decades. f(x)=2300*2^x how much is the investment worth after 2 decades?
a.$2,355,200
b. $92,000
c. $46,000
d. $9,200

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
