Best ResponseYou've already chosen the best response.0Would it be like y=2(0)^2+32(0)12 ?

Best ResponseYou've already chosen the best response.3you need to change it to the vertex form y = –2x^2 + 32x –12 = 2(x^2  16x + 6) = 2( x  8)^2 64 + 6) = 2[(x8)^2  58)] so the x coordinate at maximum = 8 a negative coefficient before x^3 means there is a maximum value
