Given:
To find:
The odd function.
Solution:
If f(-x) = -f(x), then the function is odd.
If f(-x) = f(x), then the function is even.
Option A:
Substitute x = -x
≠ - f(x)
It is not odd function.
Option B:
Substitute x = -x
(Since 
)
≠ - f(x)
It is not odd function.
Option C:
Substitute x = -x
≠ - f(x)
It is not odd function.
Option D:
Substitute x = -x
It is odd function.
Therefore, f(x) = -x is an odd function.
Answer:
Step-by-step explanation:
First we need to find the score of the incorrect answers and the questions that were not answered.
Score for the incorrect answers = 4*(-2) = -8
Score for the questions not answered = 6*(-1) = -6
Score for the questions answered correctly = 106 - [ (-8) + (-6) ]
= 106 -[-14]
= 106 + 14
= 120
Number of questions answered correctly = total score for questions that were answered correctly ÷ score of 1 correct answer
= 120 ÷ 4
= 30
30 questions were answered correctly.
Answer:
4/15 cocoa would be left if we made cookies
Step-by-step explanation:
4/6- 2/5
= 4(5)- 2(6)/30
= 20-12/30
=8/30
=4/15
The answer is: 2y^2-20y+12
