8 0

f(x) = 7x - 1

-2 = 7x - 1

-2 + 1 = 7x

-1 = 7x

x = -1/7

0 = 7x - 1

1 = 7x

x = 1/7

4 = 7x - 1

4 + 1 = 7x

5 = 7x

x = 5/7

8 = 7x - 1

8 + 1 = 7x

9 = 7x

x = 9/7

So the domain is

Domain = {-1/7, 1/7, 5/7, 9/7}

Answer:

6 units down

Step-by-step explanation:

Transformation is the movement of a point from its original position to a new position. If an object is transformed, all the point making the object is also transformed. There are four different transformations: Reflection, dilation, translation and rotation.

If y = f(x), y = f(x) + k is a translation k units up if k > 0 and is a translation k units down if k < 0

Given that the parent function is an absolute value represented by:

y = |x|

Therefore comparing y = |xl - 6 with y = f(x) + k, k < 0, therefore this is a translation of 6 units down

benjamin finds 31 pine cones at the park. Together Jenna and Ellen find the same number of pinecones as Benjamin. How many pinec

elixir [45]

Solve Step by Step:

1) Write the Equation: 31/2 = how many pine cones Jenna and Ellen found.
2) Solve 31/2= 15.5

So each girl found 15 and a half pine cones. Or one girl found 15 and the other found 16. If you want to have each girl find an even amount.
