1 Area f Learning: Mathematics Pre-calculus 12 Big Ideas Elabratins Using inverses is the fundatin f slving equatins and can be extended t relatinships between functins. Understanding the characteristics f families f functins allws us t mdel and understand relatinships and t build cnnectins between classes f functins. Transfrmatins f shapes extend t functins and relatins in all f their representatins. Transfrmatins: inverses: und the peratins within an expressin r functin t reduce the expressin t an identity (e.g., x = ) Sample questins t supprt inquiry with students: Hw can the inverse help t slve an equatin? Hw is slving an equatin related t identifying the specific input fr a functin, given a specific utput? Hw are expnential and lgarithmic functins related? Hw are the laws f expnents cnnected t the laws f lgarithms? What are sme ther examples f inversely related functins? Hw are inverses related graphically, and why? Hw is slving an expnential equatin similar t slving a trignmetric equatin? Hw are inverse peratins related t slving a plynmial equatin by factring? What is the value f using trignmetric identities t find equivalent expressins? Why d sme equatins have extraneus rts and ther equatins d nt? functins: Sample questins t supprt inquiry with students: Hw d we decide which kind f functin t use t mdel a given prblem? What d functins and relatins lk like beynd the visible axes? A set f data lks like a parabla, but it is nt. What functin culd be used t mdel this data? What des the number f zers tell us abut a functin? What cnnectins d we see within the characteristics f a particular class f functin? Sample questins t supprt inquiry with students: Hw can we tell whether a transfrmatin will have invariant pints? 1
2 Under what circumstances will different transfrmatins prduce the same result? Hw d graphical transfrmatins affect the tables f values? Hw des a transfrmatin affect a pint fund at the rigin as cmpared t a pint n an axis r a pint in ne f the fur quadrants? Hw can a ratinal functin f the frm y = ax+b be cnsidered as a transfrmatin f cx+d the reciprcal functin y = 1? x Learning Standards Curricular Cmpetencies Elabratins Cntent Elabratins Students are expected t d the fllwing: thinking strategies: Students are expected t knw the using reasn t determine winning fllwing: Reasning and mdelling strategies transfrmatins f functins and Develp thinking strategies t slve generalizing and extending relatins puzzles and play games expnential functins and equatins Explre, analyze, and apply mathematical ideas using reasn, technlgy, and ther tls Estimate reasnably and demnstrate fluent, flexible, and strategic thinking abut number Mdel with mathematics in situatinal cntexts Think creatively and with curisity and wnder when explring prblems Understanding and slving Develp, demnstrate, and apply cnceptual understanding f mathematical ideas thrugh play, stry, inquiry, and prblem slving Visualize t explre and illustrate analyze: examine the structure f and cnnectins between mathematical ideas (e.g., expnential functins t gemetric sequences) reasn: inductive and deductive reasning predictins, generalizatins, cnclusins drawn frm experiences (e.g., with puzzles, games, and cding) technlgy: graphing technlgy, dynamic gemetry, calculatrs, virtual manipulatives, cncept-based apps can be used t fr a wide variety f purpses, including: explring and demnstrating gemetric sequences and series lgarithms: peratins, functins, and equatins plynmial functins and equatins ratinal functins trignmetry: functins, equatins, and identities transfrmatins: f graphs and equatins f parent functins and relatins (e.g., abslute value, radical, reciprcal, cnics, expnential, lgarithmic, trignmetric) vertical and hrizntal translatins, stretches, and reflectins inverses: graphs and equatins extensin: recgnizing cmpsed functins (e.g., y =) peratins n functins expnential: graphing, including transfrmatins slving equatins with same base and with different bases, including base e slving prblems in situatinal cntexts gemetric: cmmn rati, first term, general 2
