| Question | Answer |
|---|---|
| How do I know when something is linear or isnt linear | its linear when the AROC is constant and isnt when its not constant RENEMBER CONSTANT MEANS SAME NUMBER NOT INCREASING BY 2 |
| how do ik when something is a quadratic | when it increaces at a constant rate its a quadratic like increaces by 2 over and over again increaces at a constant rate |
| what do you right if something is linera or non linear | blank is linear because the AROC is constant |
| what do you right if sometihing is a quadratic | blank is a quadratic beacase over equal length input value intervals , the AROC are increasing at a constant rate of 4 |
| what do you wite if it sniether | blank os niether becasue the AROC isnt constant or changing at a constant rate |
| How do you know concavity | If the AROC IS increaAsing its concave up if its decreasing concave down and if its constant noiether and if it does both niether |
| for when given one function and having to fid the multiplicity what do u do | solve for all the x if thier is an x outside the pareenthesis you HAVE TO PUT X=0 dont forget also if they give you two non factored thing factor ot find zeros also multpiclicity is the exponent of where the x is and find the degree is add all the multi.. |
| for when givin a graph and told find multiplicity | first fins x=0 then look if it goes thru its 1 if it bounces its 2 if it stayes flat its 3 |
| how to tell if a greaph is odd or even | if ittssymetrical over y its even of symetrical over the origin its odd |
| how to tell iof odd or even from function | if f(-x)=f(x) its even if its -f(x)=f(-x) its odd |
| x axis odd function is what | make both values negative |
| for even functions its y axis symetry | make -x and + y |
| AROC questions | First differences constant → LINEAR Second differences constant → QUADRATIC |
