Question 979355
Use the following formula for a horizontal parabola
4p(x-h) = (y-k)^2
the vertex is (-3,2) and parabola passes thru point (-10,1), therefore
4p(-10+3) = (1-2)^2
-28p = 1
p = -1/28 = -0.035714286 approx -0.04
p is the distance from the vertex to the focus, therefore
focus = (-3.04, 2)
