Answer:
it should be 3x^2 +2
Step-by-step explanation:
I'm in seventh grade. I haven't learned that yet.
try asking your teacher.
X2 + y2 - 14x + 10y = 250
x2 -14x + 49 - 49 + y2 + 10x + 25 - 25 = 250
(x - 7)^2 - 49 + (y+5)^2 - 25 = 250
(x-7)^2 + (y+5)^2 = 250 + 49 + 25
(x-7)^2 + (y+5)^2 = 324
Therefore the radius, r
r = 324^0.5
r = 18
-12x-20-40plus 16x
-4x plus -60
The function would be f(x)=11,500-.16xPlug in 4 for x
