Standard form for a parabola:
( x - h )² = 4 p ( y - k )
Vertex: ( h, k ) = ( -4, 2 )
Displacement from vertex to focus:
p = 2/8 = 1/4
( x + 4 )² = 4 · 1/4 ( y - 2 )
y = ( x + 4 )² + 2
or general form:
x² + 8 x - y + 18 = 0

Answer:
<GOJ
Step-by-step explanation:
O is the center of the circle
So central angle is <GOJ
F+g(x) = f(x) + g(x) = 3x-1 + x+2 = 4x+1
