Types of functions? - CORRECT ANSWER-Linear
Polynomial
Exponential
Logistic
Formula for a Linear Function - CORRECT ANSWER-L(x)=3x-6
Formula for Polynomial Function - CORRECT ANSWER-P(x)=-2x^2+3x+7
Formula for Exponential Function - CORRECT ANSWER-E(x)=2e^-0.7(x)
Formula for Logistic Function - CORRECT ANSWER-T(x)= 1000/1+4e^-0.2x
Formula for Average Rate of Change - CORRECT ANSWER-y2-y1/x2-x1
Increasing Function - CORRECT ANSWER-If the function has a positive ROC, then it is increasing.
, Decreasing Function - CORRECT ANSWER-If a function has a negative ROC, then it is decreasing.
Rate of Change for Linear Functions - CORRECT ANSWER-y=mx+b
For Linear Functions, what type of ROC are equal to the slope (m)? - CORRECT ANSWER-Average
ROC and Instantaneous ROC.
ROC in Graphs - CORRECT ANSWER-Average ROC
Instantaneous ROC
Average ROC in Graphs - CORRECT ANSWER-Find the slope of the line connecting the points
Instantaneous ROC in Graphs - CORRECT ANSWER-Measures the rate of change at one specific
time and tells us how the function is changing at that moment
What is concavity? - CORRECT ANSWER-Measures how quickly the instantaneous rate of change
of a function is changing
The function is changing slower and slower? - CORRECT ANSWER-The graph becomes flatter
The function is changing faster and faster? - CORRECT ANSWER-Graph becomes steeper
Concave up? - CORRECT ANSWER-Shaped like a U or smiley face.
Can separate concave up graphs asked on whether they are increasing or decreasing.
(Decreasing and concave up is decreasing slower and slower) (Increasing and concave up is
increasing faster and faster)
Concave Down? - CORRECT ANSWER-Upside down U or a frowning face.
