\( 6_{50} \) The number of humpback whales identified in Juan de Fuca Strait rose from 1 in 1997 to 46 in 2014 (17 years later). Assuming the population increase followed an exponential trend, create an exponential equation, and then use the equation to estimate the number of whales identified in 2020 . Round to the nearest whale.

Suppose that the polynomial function \( f \) is defined as follows. \[ f(x)=2 x^{2}(x-7)^{2}(x+1)^{3} \] List each zero of \( f \) according to its multiplicity in the categories below. If there is more than one answer for a multiplicity, separate them with commas. If there is no answer, click on "None."
