Answer:

Step-by-step explanation:
The general equation of a circle is as follows:

In which the center is
, and r is the radius.
In this problem, we have that:

So

Passing through (2,-4)
We replace into the equation to find the radius.



The equation of the circle is:

Answer:

Answer:
Local maximum = [3, 4]
Step-by-step explanation:
Step 1: Plot the given points [–1, 0] [1, 2] [2, 3] [3, 4] and draw the graph.
Step 2: Observe the graph, it is a straight line. Which has local minimum and local maximum at the closed interval.
Here with I have attached the graph.
The graphed function at local maximum at [3, 4]
Thank you.
Answer:
(3,4)
Step-by-step explanation:
A function can't have the x repeat so the only possible answer is (3,4)
