Ch 7 Test yourself, part 2

Before you do the 2nd half of this paragraph,

first .... the following slides.

Let's look back at T4

1. Work out on scrap paper!

2. Write your Answer-only on the Mini White Board,

and 3. show it when I say so!

Answer T4a:

Work out on scrap paper again:

next:

finally:

a.STUDY SQUARE is opened

b. CLASSROOMERS: we continue with this LessonUp!

Homework: 

+ finish T5 - T8

+ p.265 E7,8,9 (a still tastefull leftover!)

T5, p.263

Which Formula Form is needed?

Think of the best Form for:

answer 1st graph's Formula:

f(x) = (x - s) (x - t),

because you have the p.o.i. with the x-axis.

Think of the best Form for:

because you have:

+ the p.o.i. with the y-axis and

+ 2 other points

+ now the 'simultaneous equations' come up!

f(x)=ax​2​​+bx+c

Think of the best Form one more time:

because you know:

+  the vertex and 

+ one more point

h(x)=a(x−p)​2​​+q

Homework time:

p.263: T5 -  T8

Also check your results with the Solutionsbook.

Good luck!
