Answer:
Option C
Step-by-step explanation:
Zeros of a function are also called as x-intercepts of a function, which means where the graph/function intersects the x-axis.
In the image we see the graph intersects the x-axis at three points
x=0 , x=2 , x=4 so our answer is option C
Step-by-step explanation:
D I think sorry if it's wrong :(
Answer:
Step-by-step explanation:
Recall that on the unit circle, each point is represented as 
where 
. In this case, we are asked to take a loot at the interval 
.
We will use the definition of tangent to solve the problem. REcall that
So, in this case, tangent is undefined whenever the denominator is zero. That is, when 
. Checking the unit circle with the interval , this restriction corresponds to the upper half of the unit circle. In this case, the x component of each point is cosine. We are interested at the points where .
. This happens only at the point (0,1), which is associated with the value of
