Auzirian buys a sports car for $48,000. The value of the car depreciates by 2% each year. The car has 4 tires and is this really cool blue color. How much will Auzirian's car be worth after owning it for 7 years?

What is the initial value in the situation above?

$48,000

Tanzania owns a pair of Louboutins that are worth $1,000. Each year the value of the shoes increases by $100.

True or False: The shoe value increases by a constant rate each year.

True

Increasing by a fixed amount -> Arithmetic -> constant rate

Mia owns a vintage record that goes up 1.2% in value every year since it was released.

True or False: The record value increases by a constant rate each year.

False

1.2% increase = value(.012)

Multiplication -> geometric -> not a constant rate

300

True or False:

Exponential Functions/Geometric Sequences show a constant rate of change.

False.

Linear Functions/Arithmetic Sequences show a constant rate of change.

300

The following graph shows a linear or exponential function?

Exponential

300

Cameron opened a savings account and saves the same amount of money each month. The total amount in his account, A, after m months is given by the equation below.

A=25m+150

What does the 150 in this equation represent, in this context?

The starting amount in the account.

400

y=2/3x+3

400

Would the following multiplication produce a rational or irrational number?

2/3(7/sqrt25)

Rational

2/3(7/sqrt25)=2/3(7/5)=14/15

400

Which table shows an exponential function?

-> Table A shows a common ratio of 2

-> Table B shows a common difference of 2

500

Caiden bought a new video game where his goal is to find stars. Points are awarded as follows:

If x represents the number of diamonds found and y represents the total number of points, write an equation that models the points awarded for finding stars in this video game.

y=10x+15

Explenation:

y=d(x-1)+a

y=10(x-1)+25

y=10x-10+25

y=10x+15

500

Which table shows a function that increases at a faster rate than the others?

Table A

Reason:

-> Table A is being multiplied by 2 each time

-> Table B is adding 10 each time

--> Table A will increase faster than table B

500

Write an equation for the graph shown

y=5(2^x)

500
