Graphing vertex form*y*-*k*=*a*(*x*-*h*)²; quadratic functions; writing quadratic functions & equations; word problems - Tuesday, February 13, 2018 (24)
- Return quizzes and work on corrections
- Topic - Direct Variation (Day 1) [8.1]
- Explore direct variation with M & Ms® activity
- If
*y*varies directly as*x*, then

*y*=*k**x*

(*k*is called the constant of variation) - Notice that this also means
*y*/*x*=*k* - Here is an example of a word problem using direct variation
- Assign p 354 1-7 all (also state the value of
*k*); p 356 4-5 all, 7-17 odd for Wednesday - Wednesday, February 14, 2018 (25)
- Go over p 354 1-7 all (also state the value of
*k*); p 356 4-5 all, 7-17 odd - Topic - Inverse & Joint Variation [8.2] (Day 1)
- If
*y*varies inversely as*x*, then

*x**y*=*k*or*y*=*k*/*x*

(*k*is called the constant of variation) - Investigate inverse variation with cookie activity
- Thursday, February 15, 2018 (26)
- Go over p 356 7-17, 19
- Topic - Inverse & Joint Variation [8.2] (Day 2)
- If
*y*varies inversely as*x*, then

*x**y*=*k*or*y*=*k*/*x*

(*k*is called the constant of variation) - Here is an example of a word problem using joint variation
- A tip for word problems - "jointly" means direct variation w/multiple variables; all inverse variations will have the word "inverse(ly)" in them
- Assign p 360 1-10 all; p 361 1-2, 4 all for Friday
