Answer:
Option a is right.
Step-by-step explanation:
Parent funciton is
![f(x) = x^3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E3)
The new graph is
![f(x) = -2x^3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-2x%5E3)
Since there is no change for x, there is no horizontal shift.
BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.
Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2
Option a is right
i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.
50% = 1/2
3^2 > 2^3
-
0.5 > 0.5
Answer: 5 + 5^2 + 5^3 + 5^4
Explanation:
1) First time, when Kris forwards the e-mail it reaches other 5 people.
2) Second time, each one of the 5 people forawer to other 5 people, meaning that the second time the e-mail has reached other 5^2 people.
3) Third time, each 5^2 people forwarded to other 5 people, so the email reaches other 5^3 people
4) Fourth time => 5^4 new people.
So, the total number (not including Kris) is 5 + 5^2 + 5^3 + 5^4.
Answer:
2 (C)
Step-by-step explanation:
The "bisector" of the two sides is always equal to 1/2 of the base so...
2(3x-1) = 2x+6
Then, we simply btoh sides...
6x-2 = 2x+6
Then, we bring all the variables to one side and the numbers to the other..
4x = 8
Finally, we simplify to get our answer...
x=2 (C)
