Answer:
Increasing:
Decreasing:
Step-by-step explanation:
So when an equation has and odd degree, it will go in the opposite direction on both ends, so if y went towards infinity as x went towards infinity, then y would go towards negative infinity as x goes towards negative infinity. In this case, by looking at the graph it has an odd degree, due to opposite end behaviors, although on both ends it's increasing because even though it appears that it's going down on the left side, that's only if you start from the right and go towards the left. So it's really increasing from negative infinity to -1, and then it decreases from -1 to 2, until it once again starts increasing from 2 to infinity. This can be represented as (-infinity, -1) U (2, infinity) for increasing and (-1, 2) as decreasing
Answer:
x= 30
Step-by-step explanation:
The angles shown are corresponding, meaning that they are equal in measure. To find the answer, set x+25 equal to 55. Solve. x=30.
(x+25)=55
(30+25)=55
To land on 0 the number would need to end with a .5 or .0 since that is the only way .0 can occur with counting down by.5( half)
is supposed to be a function such that
In this case, we need
To recover from , we would first need to raise to the third power:
Then add 2:
To recap, we carried out
which implies that the inverse function is
To verify: we should also have that . We get
