Consider the following scenario: Suppose the RotoMod smartphone debuted with great fanfare, but negative word of mouth about its hard-to-use interface curtailed sales. The number of phones sold x months after its release can be modeled by

f(x) = 5.38 2.13 ln(x) 1 x 12

where x represents the number of months since the smartphone was released for sale and

f(x)

represents the number of smartphones sold, in thousands.How many smartphones were sold in the first month? smartphones
