#1**+2 **

Here's the first two

When x = 3, y = 3.5 = ( 3, 3.5)

When x = 6, y = 9 = ( 6, 9)

So....the average rate of change is like the slope between two points and is given by

[9 - 3.5 ] 5.5 55 11

_______ = ____ = ____ = ___

[6 - 3 ] 3 30 6

For the second one.....the independent variable = Side Length

And the dependent variable = Area

For the last one, set the listed factors to 0 and solve for x.....this must produce 2/3

So

2x - 3 = 0 add 3 to both sides

2x = 3 divide both sides by 2

x = 3/2 no!!!

The second and fourth answers will produce negative answers for x

But.....notice that....

3x - 2 = 0

3x = 2

x = 2/3 and "C" is the one we want
