solve for part c

Suppose the total value for a cryptocurrency (in billions of dollars) was $105 in January 2020 and $750 in January 2021. Complete parts (a) through (c) (a) Find an exponential function of the form fit) = ygb! to model these data with t in months, where t=0 corresponds to January 2020. f()= 105+ (1.178) (Use integers or decimals for any numbers in the expression. Round to three decimal places as needed.) (b) If the model remains accurate, what would have been the predicted value for February 2021? If the model remained accurate, the predicted value would have been $ 883 billion (Round to the nearest whole number as needed.) (c) By experimenting with different values (or using a graphing calculator to solve an appropriate equation), estimate the first full month in which the value of the cryptocurrency exceeded $389 billion The first full month in which the value exceeded $389 was in [yy of the year (Type a whole number.)
