Question 831295: Please, oh please help me solve this horrible word problem!
Solve:
Caladan is currently one of the world's fastest-growing countries. The exponential function f(x)=143(1.028)^x models the population of Caladan, f(x) in millions, x years after 1974. Using this exponential function and a calculator with a y^x key or a ^ key, answer the following questions.
a. Substitute 0 for x and, without using a calculator, find Caladan's population in 1974.
b. Substitute 25 for x and use your calculator to find Caladan's population in the year 1999 as predicted by this function.
c. Find Caladan's population in the year 2024 as predicted by this function.
d. Find Caladan's population in the year 2049 as predicted by this function.

You can put this solution on YOUR website! Caladan is currently one of the world's fastest-growing countries. The exponential function f(x)=143(1.028)^x models the population of Caladan, f(x) in millions, x years after 1974. Using this exponential function and a calculator with a y^x key or a ^ key, answer the following questions.
--------------
a. Substitute 0 for x and, without using a calculator, find Caladan's population in 1974.
f(x)=143(1.028)^x
f(x)=143(1.028)^0
f(x)=143*1
f(x) = 143
Was that hard?
---------------
b. Substitute 25 for x and use your calculator to find Caladan's population in the year 1999 as predicted by this function.
Just use a calculator.
============================
c. Find Caladan's population in the year 2024 as predicted by this function.
x = 2024 - 1974 = 50
Use a calculator.
=====================
d. Find Caladan's population in the year 2049 as predicted by this function.
x = 2049 - 1974
============================================
That's hardly a word problem, just some calculator work.
