Answer:
O the circumcenter is equidistant to all three vertices
Step-by-step explanation:
Answer:
refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
Answer: Option D
phase
Step-by-step explanation:
By definition, the cosine function has the following form

Where
is known as the phase angle
By definition the sinx function is equal to the cosx function with a phase shift of 
So if we have the function
and we want to transform it into the function
then 
Finally
the answer is the option D
Answer:
See step by step
Step-by-step explanation:
To find if a function intervals are possible, make sure the points are above the x axis.
The graph is getting positve around x=-3 but it isn't positive yet.
The graph is positve until x=-1
The graph becomes positive again again at x=2 and is positive infinitely forever.
So let set up our interval
We are going to start at -3 since that where it start getting positive, we then going to use the greater than sign since it get positve as we go to the right as of right now. We use the greater than becuase we are not going to include -3 as our solutions.
We then use a less than sign since the answer must be less than -1 becuase around-1 it start getting negative.
It becomes positive again at x=2 so since we going to left to right use the greater than sign becuase we are not including 2.
It infinitely becomes positive so our interval is x must be cause greater than w becuase it can be any interval greater than two.

and

The roots or zeroes are the x intercept of the graph,(when y=0, what is the x value.)
The x intercepts are -3 and 2.
Answer:
x =8/9 i dont know if im correct
