Answer:
You start at -9
-Open circle
-shade towards the right (where all the positive numbers are)
Open circle - ones that don't have a greater than or equal to. If it does then it's a closed one.
Shade towards the right cause y is less than 9
Answer:
The slope is the number with the varible next to it.
Step-by-step explanation:
1. 2x
2. 5x
3. 2/3x
4. x
5. x
Your insight that the function values differ by 5 every time is very important. So your f(x) will contain 5x as a term. You have to find a constant to add or subtract to make sure f(1)=-2.
f(x) = 5x-7 does the job.
R= 18
d=r(2)
36=r(2)
36/2=r(2)/2
18=r
