Explanation:
#"the equation of a parabola in "color(blue)"vertex form"# is.
#color(red)(bar(ul(|color(white)(2/2)color(black)(y=a(x-h)^2+k)color(white)(2/2)|)))#
#"where "(h,k)" are the coordinates of the vertex and a"#
#"is a multiplier"#
#"take out a factor of 3 from "(3x-4)^2#
#rArry=3(x-4/3)^2-7larrcolor(blue)"in vertex form"#
#"with "h=4/3" and "k=-7#
#rArrcolor(magenta)"vertex "=(4/3,-7)#
