Algebra 2 Recap
2
Based on yesterday's test
We need to recap what we've learned this year...
3
Sequences
Find the pattern in the list of numbers
4
Multiple Choice
Find the next three terms in this sequence: 10, 14, 18, 22
28, 34, 40
Repeat the pattern
26, 30, 34
Add 4
Not enough information
5
Multiple Choice
What is the pattern (change) for the following sequence: -4, 8, -16, 32
multiply by 2
add 4 then times 2
multiply by -2
6
Geometric or arithmetic?
Geometric : multiply (or divide)
Arithmetic : add (or subtract)
7
Multiple Choice
For the sequence: -1, -2, -4, -8, -16, state if is arithmetic, geometric or neither
Arithmetic
Geometric
Neither
8
Closed form
Always start with your first term, and then end with the pattern
9
Multiple Choice
Write the closed form for the sequence: -4, 11, 26, 41
A(n) = -4 + 15n
A(n) = -4 - 15n
A(n) = -4 + 11
A(n) = -4 - 11n
10
Recursive formula
always in the form f(n) = f(n - 1) and then the pattern
11
Multiple Choice
Write the recursive form for the sequence: 6, 12, 18, 24, 30 ...
f(n) = f(n - 1) + 6
f(0) = 6
f(n) = f(n - 1) * 6
f(0) = 6
f(n) = f(n - 1) * 2
f(0) = 6
f(n) = f(n - 1) + 2
f(0) = 6
12
Finding slope of a line
Slope is the rate of change, with the ratio runrise or
change xchange y
13
Multiple Choice
What is the slope of this line?
m=21
m=−4
m=2
m=−21
14
Multiple Choice
Find the slope between the two points: (-1, -5) and (-2, -6)
m=1
m=5
m=113
no picture, can't do it
15
Multiple Choice
Solve for x:
6(3x−1)−(−3x+7)=29
x = 6
x = 2
x = 29
not enough info
16
Multiple Choice
Find the x-intercepts for this equation (write as an ordered pair)
y=−16x+8
(21 , 0)
(0, 168)
(0 , 21)
(0, 0)
