§7.6 Tables and formulas 
is today's meal.
 
First we have one more bite at §7.5 Square root formulas!

Slide 1 - Diapositive

For the next questions:
+  calculate the Boundary point on scrap paper, and
+  choose the right answer on the Multiple Choice slide!

Slide 2 - Diapositive

Find the Boundary point for:

Slide 3 - Diapositive

The boundary is .....
y=(102x)13
A
(-13, 5)
B
(10, -13)
C
(5, -13)

Slide 9 - Diapositive

Now...
we start with §7.6, in which you will see back all
relations between x and y that were dealt with earlier in this chapter!
