A certain bacteria population doubles every 20 minutes. Beginning with 10 cells in a culture, the population can be represented by the function B = 10(2), where B is the number of bacteria cells and t is the time in 20 minute increments. How many will there be after 2 hours?

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
