Graph P=619(1.12)^t

Question

the population of winnemucea,Nevada can be modeled by P=619(1.12)^t where t=0 refers to 2009

Answer 1

This is an exponential graph in the form y=ab^x, where a =619 and b= 1.12.  The y axis is the population and the X axis is the year.  Your first 4 ordered pairs are (1(aka 2010),693), (2,776), (3,870), (4,974). The y value for each ordered pair is 12% more than the previous value.
