Quizes

General forms of a sequence

Arithmetic and geometric sequences

Arithmetic formula: an=a1(n+1)d

Geometric formula: an=a1*r(n-1)

A sequence is a list of numbers

Geometric example:
2,4,8,16,32,64
They all are divided by 2

Arithmetic example:
2,4,6,8,10,12,14
They are all +2

graphing exponents

Graphing exponential growth and decay

• domain are always going to be all real numbers in growth or decay
• asymptote = k
• range is either y is greater than k or less than k 
• to graph, make the t chart table and then graph the points

Statistics

Statistics Data

Compound interest formula

A = amount
P = principal
R = rate of interest
N = number of times per year
T = time in years

Characteristics and traits

• Domain – x values
• Range – y values
• End behavior – x→-∞,y→∞ or -∞
• Absolute max/min - 1 highest/lowest point
• Local max/min - more than one lowest/highest point
• interval of increase/decrease - what happens to a graph (y values) as you move along the x axis if y values are increasing
• x intercept - the point that crosses the x axis
• y intercept - the point that crosses the y axis
• symmetry - if it is symmetric around the origin or the y axis
• even/odd/neither - even;symmetric around y axis                                           odd; rotation around origin          neither; none
• function - a function is an equation that passes the vertical line test
• one to one - passes the horizontal line test
• assymptotes - the line that gets close to the x axis but never touches it

         

x intercept - the point that crosses the x axis

y intercept - the point that crosses the y axis
