Question

will give medal and fan.

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)

Answer 1

Actually if someone could check because im 99% sure its B

Answer 2

yup u r correct...
