Identify the quadratic function(s). (select all that apply.) 8 - 5x = 4(3x - 1) (4a + 2)(2a - 1) + 1 = 0 2y + 2(3y - 5) = 0 2b(b - 7) + b = 0

Can someone check my answer? you : )

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.
