Answer:
(x +4)^2 + (y-7)^2 = 36
Step-by-step explanation:
The equation of a circle is of the form
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x- -4)^2 + (y-7)^2 = 6^2
(x +4)^2 + (y-7)^2 = 36
I think the answer is 31.75
We will plug in -5 for x in the original equation
g(-5) = (-5)^2 - (-5)
we will first square -5
g(-5) = 25 + 5
g(-5) = 30
