A petri dish contains cells of a certain strain of bacteria. Each bacterial cell in the dish divides in half approximately every 6 minutes. The curve of best fit that models the number of bacterial cells in the dish is given by the equation Rx) = 4.2.1.1%, where x represents the number of minutes

and y represents the number of cells. Approximately how many bacterial cells will be in the petri dish after 30 minutes?

A. 22 cells

B. 37 cells

C.

73 cells

D.

126 cells
