North Dakota has recently had the fastest growing population out of all 50 states. On Jan 1, 2013, the population of North Dakota was 700,000 people. North Dakota’s population has been growing by 5% per year. Express North Dakota’s population, N, in terms of years since 2013, t.

Check the BEST answer:

• N=700,000(1-0.05)^t

• N=700,000(0.95)^t

What is the equation of the graph below?

• f(x ) = I x + 4 I + 2
