A.

Linear
B.

Exponential
C.

Discrete
D.

Continuous
E.

Increasing
F.

Decreasing
G.

Arithmetic
H.

Geometric

Correct Answer(s)
A. Linear
C. Discrete
E. Increasing
G. Arithmetic

Explanation
This graph is linear because the dots are in a straight line.
It is discrete because it is just dots.
It is increasing because as you go right, the values go up.
It is arithmetic because it is adding by a common difference and forms a straight line.

Reading a Problem/Situation:Harry Potter started his first year at Hogwarts knowing 5 spells already. Each week, he learned 3 new spells. This situation begins at time . This situation is . It has a common difference of .

Correct Answer(s)
0
arithmetic, linear, adding, increasing, going up, discrete, continuous
d=3, d = 3, d= 3, d =3

Explanation
This situation begins at time 0 because it says Harry already knew the spells before his first year started. This is an "at the beginning" situation.
This situation in increasing (you may have used other words) with a common difference. Depending on how you think Harry learns, it may be discrete (if you are counting spells) or continuous (if you are measuring learning).
The common difference for this situation is d=3. If you forgot to put "d=" it is incorrect!

F(n) = 5 + 3(n-0) f(15) = 50

A.

True
B.

False

Correct Answer
A. True

Explanation
If you plug in 15 for n, you would get..... f(15) = 5+3(15-0) ............ f(15) = 5+3(15)............ f(15) = 5+45............. f(15) = 50

Which of the following equations represents this table?

A.

F(n) = 2 - 2(n+1)
B.

F(n) = 2 x 2^(n-1)
C.

F(1) = 2 + 2 (n-0)
D.

F(n) = 2 x 2^(n-0)

Correct Answer
B. F(n) = 2 x 2^(n-1)
