Answer:
The function is decreasing in the following intervals
A. (0, 1)
C. (2, pi)
Step-by-step explanation:
To answer this question, imagine that you draw lines of slope m parallel to the function shown at each point.
-If the slope of this line parallel to the function is negative for those points then the function is decreasing.
-If the slope of this line parallel to the function is positive for those points then the function is increasing.
Observe in the lines drawn in the attached image. You can see that they have slope less than zero in the following interval:
(0, 1) U (2, pi)
Therefore the correct option is:
A. (0, 1)
C. (2, pi)
Xy = -14
x + y = -3
x + y = -3
2.53 + y = -3
- 2.53 - 2.53
y = -5.53
(x, y) = (2.53, -5.53)
x + y = -3
-5.53 + y = -3
+ 5.53 + 5.53
y = 2.53
(x, y) = (-5.53, 2.53)
The two numbers that multiply to -14 and add up to -3 are -5.53 and 2.53.
x + y = -3
x + y = -3
2.53 + y = -3
- 2.53 - 2.53
y = -5.53
(x, y) = (2.53, -5.53)
x + y = -3
-5.53 + y = -3
+ 5.53 + 5.53
y = 2.53
(x, y) = (-5.53, 2.53)
The two numbers that multiply to -14 and add up to -3 are -5.53 and 2.53.
