Slide 14 - Tekstslide

T5, p.263
Which Formula Form is needed?

Slide 15 - Tekstslide

Think of the best Form for:

Slide 16 - Tekstslide

answer 1st graph's Formula:
f(x) = (x - s) (x - t),
because you have the p.o.i. with the x-axis.

Slide 17 - Tekstslide

Think of the best Form for:

Slide 18 - Tekstslide

because you have:
+ the p.o.i. with the y-axis and
+ 2 other points
+ now the 'simultaneous equations' come up!
f(x)=ax2+bx+c

Slide 19 - Tekstslide

Think of the best Form one more time:

Slide 20 - Tekstslide

because you know:
+  the vertex and 
+ one more point
h(x)=a(xp)2+q

Slide 21 - Tekstslide

Homework time:
p.263: T5 -  T8
