Answer:
A
Step-by-step explanation:
First, put this equation in slope intercept form.

Where m is the slope and b is the y intercept.

Since it's greater than, the solution set is above the line, effectively eliminating graph D.
Now we should graph it.
We can see that the point
is on the graph, and only Graph A has that point. Therefore, Graph A is the correct graph.
Answer:
c. 6
Step-by-step explanation:
Given
See attachment for graph
Required
Average rate of change
This is calculated as:

Where

So, we have:


Using the attached graph, we have:


So, we have:



Answer:
(x + 8)(x - 2)(4x - 1)
Step-by-step explanation:
Given that x = - 8 is a zero then (x + 8) is a factor
Divide f(x) by (x + 8) using Synthetic division
- 8 | 4 23 - 70 16
↓ - 32 72 - 16
---------------------------------
4 - 9 2 0
Quotient = 4x² - 9x + 2 = (x - 2)(4x - 1)
Thus
f(x) = (x + 8)(x - 2)(4x - 1)
