Step-by-step explanation:
you substitute the given values in s-row for s in the function, then calculate the results and fill the blanks in f(s)-row
s=0 --> f(s) = |0-2| / (0-2) = -1
s=1 --> f(s) = -1
s=9/2 --> f(s) = 1
s=11/2 --> f(s) = 1
s=6 --> f(s) = 1
In fact, there's a more shorter way to do this
You see that:
|x-2| = x-2 when x≥2
|x-2| = -(x-2) when x<2
Therefore:
f(s) = 1 for all x≥2
f(s) = -1 for all x<2
Answer:
D= {-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6}
R={-6,-5,-4,-3,-2,-1,1,2,5)
1/5,3/10
just look at the picture
The answer should be A and C because they are the same question
I just looked at the equations and solved it from there
x = 4
-3x + 2 = -10x + 30
Add 10x to both sides and you get
7x + 2 = 30
Subtract 2 from both sides and you get
7x = 28
Divide both sides by 7 to get x by itself and you get
Reminder whatever you do to one side you have to do to the other side!
Hope this helps!
