3.(03.06) Using the completing-the-square method, rewrite f(x) = x2 + 4x – 1 in vertex form. (2 points)
O f(x) = (x + 2)2 + 1
O f(x) = (x + 2)2
O f(x) = (x + 2)2 + 4
O f(x) = (x + 2)2-5

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
