Question
If a graph is a parabola ["horseshoe shape or U"] opening up with a
vertex [starting point] at (4, 2) that only crosses the y-axis once at
(0,18) [it never crosses the x-axis]:
find the quadratic function for this graph, using the form
f (x) = a(x – h)² + k, with a = 1 here.
O (z - 4) + 2
ㅇ (z+ 4)2 + 2
ㅇ(z+ 4)2-2
O (z - 4) - 2
O (z + 18)² – 4
