Chapter 3 Test

Evaluate:

Evaluate:

### Problem 3

Solve for x (round to the hundredths):

### Problem 4

Write the equation of an exponential function that goes through (0,5) and (2,12).

### Problem 5

Given:

What is the y-intercept?

### Problem 6

Given:

What is the limit to growth and the horizontal asymptotes?

Simplify:

### Problem 8

List the transformations (in order) of

Basic:

VerticalHorizontal

Solve for x:

### Problem 11

Write a logistic function if:

Initial value = 20, Limit to growth = 200, Passes through (2,32)

Solve for x:

Solve for x:

### Problem 14

The population of a town is 10,000 in 1980. It is increasing at a rate of 2.9% each year. Determine the exponential equation to find when the population will reach 30,000 people.

### Problem 15

The half-life of a substance is 2 minutes. The original mass is 20 grams. How much of the substance remains after 5 minutes?

### Problem 16

How long will it take your investment to double if it earns 7.5% compounded quarterly?

### Problem 17

P. J. purchases furniture for \$25,000. What are his monthly payments for a 3-year loan with a \$5,000 down payment if the APR is 2.8%?

### Problem 18

Which is a better investment: 5.25% compounded quarterly or 5.15% compounded monthly? (Hint: Find APY for both!)
