Question

Which graphı represents a circle whose equation is u + 3x + 1) = ?

Answer 1

Graph A

Step-by-step explanation:

The equation of a circle has the following form:

`(x-h)^2+(y-k)^2=r^2`

Where (h, k) are the coordinates of the center and r is the radius of the circle.

So, if the equation is:

`(x+3)^2+(y-1)^2=4_{}`

We can rewrite the expression to get:

`(x-(-3))^2+(y-1)^2=2^2`

Now, if we compare the equations, we can identify that the center is the point (-3, 1) and the radius is 2.

Therefore, the only option that satisfies both conditions is A. So, the answer is graph A.
