Answer:
D. 
Step-by-step explanation:
Consider parent function 
The graph of this function is the same as the graph of the function 
because the tangens has period of 
(See first attached diagram)
Now, you can see that the graph of the function 
is translated 2 units up. This translation gives you the function (see second attached diagram)
Answer:
b. 
Step-by-step explanation:
The graph can be divided into 4 regions.
Region 1 is for 
Region 2 is for 
Region 3 is for 
Region 4 is for 
So, for the region 1, the values of 
goes on decreasing with increasing 
. Therefore, the function is decreasing in the interval 
.
Now, for the region 2, the values of increases with increasing . So, the function is increasing in the interval 
.
For the region 3, the the values of goes on decreasing with increasing . Therefore, the function is decreasing in the interval 
.
Now, for the region 4, the values of increases with increasing . So, the function is increasing in the interval 
.
Therefore, regions 2 and 4 are the regions when the function is increasing.
Hence, the correct option is b.

Step-by-step explanation:
Roberto has twice the mass his sister Mary has but runs at the same velocity as Mary. Will his kinetic energy be twice as much?
(Mary has a mass of 40 kg and sprints at 1 m/s)
Can someone help me with this (sorry I don’t have enough point for a question and no one has answered this and I’m confused)
