Vertex Form: Y = a(x-h)^2 + k.
A. The parabola opens upward because "a"
B. Y = (x-3)^2 - 2.
Let X = o and solve for Y:
Y = (0-3)^2 - 2 = 7. = Y-int.
C. Let Y = 0 and solve forX:
Y = (x-3)^2-2 = 0.
(x-3)^2 = 2
Take sgrt of both sides:
x-3 = +-sqrt2
X = +-1.414 + 3 = 4.14, and 1.59. = X-intercepts.
D. V(h,k) = V(3,-2).
E. Select values of X below and above
h and calculate the corresponding value of Y.
(x,y). Y = (x-3)^2 - 2.
