You can put this solution on YOUR website!
given f(X)=-X^2+4X-1
y+1=-x^2+4x
x^2-4x=-(y+1)
x^2+4x+4=-(y+1)+4
(x+2)^2=-(y+1-4)
(x+2)^2=-(y-3)
find the y intercept=(0,-1)
find the equation of the axis of symmetry: x=-2
find the coordinates of the vertex_(-2,3)
make a table of values. x_I'll leave this to you______
y______________________________
Determine whether the function has a maximum of mimimum value._maximum
