find and label the vertex and line of symmetry. graph the function
f(x)=1/4x^2
F(x) = 1/4X
Vertex form: Y = a(X - h)^2 + K
Y = 1/4(X - 0)^2 + 0
V(h,k) = (0,0)
To graph a parabola, select 2 or 3
values of X on each side of vertex.
Then calculate the corresponding
value of Y:
(-4,4),(-2,1),V(0,0),(2,1),(4,4).
Line of symmetry: h = x = 0. So the
line of symmetry is a vertical line
on the Y-axis.
