What is the vertex of #y=2(x-2)^2-9 #?

Answer 1

Isaiah Anthony

#(2,-9)#

#"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"#

#y=2(x-2)^2-9" is in vertex form"#

#rArrcolor(magenta)"vertex "=(2,-9)#
