Answer: (0,0) or y=0
In order to find the y-intercept, we need to find the point that crosses the y-axis. To find that x=0 or (0,y)
When x=0, y=0 on the graph since there are no transformations.
Answer:
the first one is correct

To find increasing and decreasing intervals we take derivative
Now we set the derivative =0 and solve for x
sinx + cosx =0
divide whole equation by cos x

tanx +1 =0
tanx = 1
and
Now we pick a number between 0 to 
Lets pick 
Plug it into the derivative
= 4.810 is positive
So the graph of f(x) is increasing on the interval [0,
)
Now we pick a number between
to 2pi
Lets pick 
Plug it into the derivative
= 116 is positive
So the graph of f(x) is increasing on the interval 
Increasing interval is 
Decreasing interval is 
(b)
The graph of f(x) increases and reaches a local maximum at 
The graph of f(x) decreases and reaches a local minimum at 
(c)
f(0) = 0



Here global maximum at 
Here global minimum at
