I’m gonna die help Plz answer I asked this question for 2 hours answer now plz

What is the axis of symmetry of f(x) = -x^2 4x + 12

axis of symmetry is x = 2

how did you get your answer show work

x = -b/2a = (answer)

show work for the answer 2 which is the axis of symmetry

plz help answer if u know only
if u dont know dont asnwer dont answer for poins or i will report if do

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
