1. Identify the initial amount a and the rate of growth r (as a percent) of the exponential function y=350(1+0.75)^t . Evaluate the function when t=5 . Round your answer to the nearest tenth. a= __ r= __% when t = 5 , y = __

2. determine wether r (t) = 0.4 (1.06)^t represents exponential growth or exponential decay.
- this function represents; exponential decay, exponential growth, or neither growth nor decay
- identify the perent rate of change = __%

3. write a function in terms of t that represents the situation; your starting annual salary of 35,000 increased by 4% each year
y= __

4. identify the initial amount a and the rate of growth r (as a percent) of the exponential function y= 25 (1.2)^t. evaluate the function when t=5. round your answer to the nearest tenth.
a= ___ r=___ when t=5 , y= ___

5. write a function in terms of t that represents the situation. a population of 210,000 increases by 12.5% each year
y=
