Linear and Exponential Functions Module 2

The value of a painting is $12,000 in 1990 and increases by 8% of its value each year.  Write and evaluate an expression to estimate the paintings value in 2005.

• 1.08(12,000)^t = $36,000
• 12,000(1.08)^t = $38, 066
• 12,000(0.5)^t = $10,000
• 12,000(0.92)^t = $40,000

Challenge 2:
Which statement below describes the comparison of rate of change between the linear function f(x) and the exponential function g(x). 

• g(x) rate of change is ALWAYS greater than f(x) rate of change. 
• g(x) is NEVER greater than f(x) rate of change. 
• g(x) will eventually exceed the rate of change of f(x). 
• There is not enough information to compare the rate of change of f(x) to g(x). 

Write a rule:  A plumber charges $50 for a house call plus $12 per hour for labor.

• y = 50x + 12
• y = 50 + 12x
• y = 62x
• x = 50 + 12y
