CHANGING AN EQUATION TO SHIFT ITS GRAPH
VERTICAL AND HORIZONTAL SHIFT FORMULAS (cɬ)
DEFINITIONS
STANDARD EQUATION FOR THE CIRCLE OF RADIUS r CENTERED AT POINT C(h, k):
INTERIOR OF A CIRCLE
EXTERIOR OF A CIRCLE
PARABOLA
PARABOLA THAT OPENS UPWARD
AXIS OF SYMMETRY
VERTEX
y = x2 / 4p
PARABOLAS THAT OPEN DOWNWARD
y = -x2 / 4p
y = ax2
y = a(x - h)2
y - k = a(x - h)2
y = ax2 + bx + c, a = 0
SOLUTION… y = (-1/4)x2 + 2x + 4
PARABOLAS THAT OPEN TO THE RIGHT OR LEFT
x = ay2
SOLVING x = y2 FOR y
