What is the axis of symmetry of h (x) = 6x2 - 60x + 147? x = - 5 x = - 3 x = 3 x = 5

If you use a graphing calculator or desmos online and punch in " y=6x^2-60x+147 " there will be a graph. There will be a middle dot. If you put you click it, it will show up (5,-3). Because the axis of symmetry is always the x variable then it would be the last choice. x=5

X=5 the last answer, Because after writing it in vertex form it is in the place of K
