The equation of a circle is
what are the coordinates for the center of the circle and the length of the radius

The answer is

Step-by-step explanation:

The general equation of a circle is given by

where the center of the center of the circle is given by

From the question the equation is

x² + y² + 14x + 2y + 14 = 0

Comparing with the general equation above we have

2g = 14 2f = 2

g = 7 f = 1 c = 14

So the center of the circle is

The radius of a circle is given by

where

g = 7

f = 1

c = 14

Substitute the values into the above formula

That's

we have the final answer as

Hope this helps you

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

x + 4/7
