*The first way, find the xvertec by use formula x=b/2a = 8/2(2) = 2 to find the max value, just plug x=2 to P(x) so, P(2) = 2(2)^2+8(2)1=7 *The 2nd way, use the formula y=D/4a (with D=b^24ac) y_max = (8^24(2)(1))/4(2) = (648)/8 = 56/8 = 7

you dont even need calculus, just use the vertex formula you learn in algebra. you know it is a parabola that opens down, so you will have a max value. it will be the y component of the vertex
