1 answer:
Answer:
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 )
