Find the axis of symmetry and vertex for the following equations. y=-x^2-4x+1

hello :

the axis of symmetry  is the line wher an equation is : x =2

the vertex is : (  2 ; 5 )

Step-by-step explanation:

write this expression in the vertex form :

y=-x²-4x+1

y = - ((x² +4x +4) -4) +1

y = - (x -2)²+5

the axis of symmetry  is the line wher an equation is : x =2

the vertex is : (  2 ; 5 )

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
