Answer:
Yes, this is a function.
Step-by-step explanation:
To have a function, each value used for the x-coordinates can be used only once.
Let's look at all the x-coordinates: -5, -3, -1, 1, 3, 5.
All x-coordinates are different. No value in the x-coordinates is used more than once.
Answer: Yes, this is a function.
Answer:
How are u supposed to do this
Step-by-step explanation:
What are the angles?
x > -1
-2x+5 < 7
-2x<2
Now since you divide by (-1) to get positive 2,you need to flip the sign
(-2)/(-1)= 2 2/(-1)=-2
SO
2x>-2
x > -1
To check the solution do not replace the x by -1 because it shouls be more than -1 (You can choose 0,1,2,3....)
Example choose x=3
-2x3+5<7
-6+5<7
-1<7
