Please help me find the vertex and intercepts for this quadratic function, and help me to sketch its graph.
y = x^2 - 6x
Y=(X-3)^2-9...THIS HAS VERTEX AT X=3 AND ITS VALUE IS
Y=(3-3)^2-9=-9
GRAPH IS OBTAINED BY GIVING DIFFERENT VALUES TO X AND INDING THE CORRESPONDING VALUES OF Y AND PLOTTING THEM TO A SUITABLE SCALE
X=........0........1.........2...........3..........ETC.....
Y=X^2-6X..0........-5........-8..........-9.........ETC....
THE GRAPH WILL LOOK LIKE THIS
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C+x%5E2-6x%29+
