Answer:
(x+1)² + (y-4)² = 10
Step-by-step explanation:
The diameter of a circle has the endpoints at (2,3) and (-4,5).
Therefore, the length of the diameter is given by
= 2
Hence, the radius of the circle is √10.
Now the midpoint of the line joining (2,3) and (-4,5) will be the center of the straight line.
Hence, the center will be at (
Therefore the equation of the circle is
(x+1)² + (y-4)² = (√10)²
⇒ (x+1)² + (y-4)² = 10 (Answer)
<h2>Answer:</h2>
First of all, let's define what a function is:
A function from a set
to a set
is a relation that assigns to each element
in the set
exactly one element
in the set
. The set
is the domain (also called the set of inputs) of the function and the set
contains the range (also called the set of outputs).
The ordered pairs has been plotted below. As you can see, the set B is the only relation that meets the requirements of the concept of function because that relation assigns each element in the set
exactly one element
in the set
. For the other sets, at least one element
in the set
matches to two or more elements
in the set
.
