Write the following into the form of
and find the vertex, the symmetric axis and y-intercept
a)
Vertex = (-1,-2), Symmetric, x=-1, y-intercept, when x=0, y=-1
Am i doing the correct method to calculate ??
b)
Vertex = (2,3), symmetric x=2, y-intercept=-1
c)
Vertex (-1,-6), symmetrix =-1, y-intercept=-6
am i correct ?
