b) Number of students present vs. number of empty chairs in a classroom

c)Outside temperature vs. Number of drinks sold at Dollywood

d) calorie intake vs. wieght

Which of the following graphs represents the function f(x) = 2^x

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

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
