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)
