Rewrite the equation in vertex form. name the vertex and y-intercept.
y = x^2 – 10x + 15
y = (x – 10)^2 –10
vertex: (–10, –10)
y-intercept: (0, –10)
y = (x – 5)^2 – 10
vertex: (5, –10)
y-intercept: (0, 15)
y = (x – 5)^2 + 40
vertex: (5, –10)
y-intercept: (0, 15)
y = (x – 10)^2 + 20
vertex: (–10, –10)
y-intercept: (0, –10)
