Answer:
Step-by-step explanation:
First find the midpoint of the segment from (2, -6) to (-4, -16)
((2 - 4)/2, (-6 - 16)/2)
(-2/2, -22/2)
(-1, -11) is the midpoint and is the center of the circle
Now find the distance between the 2 given points and divide by 2 to get the radius of the circle
d =
=
=
=
r = /2
= 136/4 = 34
Equation of circle with center at (-1, -11) and radius = is
Answer:
Discontinuity at (-4,-2), zero at (-2,0).
Step-by-step explanation:
We are given that a function
We have to find the discontinuity and zero of the given function.
Discontinuity: It is that point where the function is not defined.
It makes the function infinite.
When x=-4 then
It is indeterminate form
Function is not defined
After cancel out x+4 in numerator and denominator then we get
Substitute x=-4
Therefore, the point of discontinuity is (-4,-2).
Zero: The zero of the function is that number when substitute it in the given function then the function becomes zero.
When substitute x=-2
Then ,
The function is zero at (-2,0).
Hence, option C is true.
