What's another term for Average Rate of Change?
Slope
(x + 1) (x + 2)
x2 + 3x + 2
Name the 3 different types of studies for statistics we talked about?
Experiment, Observation, Survey
What is the slope of a line passing through the points (1, 2) and (3, 30)?
14
Factor- x2 - 9x - 90
(x-15)(x+6)
What's the word that we look for to represents independent/dependent events?
Replace, without replacement
Which Function do we have that will exceed all other functions and why?
Exponential, the exponent is the one that changes everytime making it have a greater rate of change.
3x(2x + 1) (3x + 4)
18x3 + 33x2 + 12x
x2 -3x -9= 2x + 1
-1.53 and 6.53
How much % lie between 2 standard deviations?
95%
Is the function 3(0.83)x increasing or decreasing? And by what rate?
Decreasing, 0.17 or 17%
If (x - 3) divides evenly into x2 - x - 6 then what is the value of f(3)?
0
(x + 2)/(x - 4) = x
-0.37 and 5.37
What is the probability of pulling a king from a deck of cards then not replacing it and pulling a 3 of spades?
1/663
What functions did we talk about this semester? Must get at least 4 correct
Linear, Quadratic, Exponential, Rational, Absolute Value, Polynomials (cubic, quartic, etc.)
Non Calculator- Factor 7x2 + 12x +5
Remember bottoms up
(7x + 5)(x+1)
Solve for x: x2 - 5 = 20
x = 5,-5
