HELP!!!!!
Part B
g(x)=−2x2+8x+3 (the second 2 is a exponet)
Write the function g(x) in the form y=a(x−h)2+k . Write the equation for the line of symmetry for the graph of g(x). Show all your work and explain your answer.
Solve for the x-max or h :\ [tex]-b/(2a)=-8/(2*-2)=2=k[/tex] plug it in to equation to get k:/ [tex]y(2)=-2(2)^2+8(2)+3[/tex] -8+16+3=11=k [tex]y=a(x-2)^2+11
[/tex] solve for a by pluging (0,0) then a= -11/4 [tex]y=-11/4(x-2)^2+11[/tex]
