Question

.

Answer 1

knowing that vertex form is y = (x-h)^2+k, what is the vertex? Hint: The vertex is (x,y), which is the same as (h,k).

Answer 2

*vertex form is actually "y=a(x-h)^2+k"

Answer 3

Have you drawn the requested graph?

"Identify the x-intercepts by graphing the quadratic equation."

Answer 4

Note in the vertex form:
y=a(x-h)^2+k
h has a lowered minus sign (-) in front of it.

Answer 5

yeah, @skullpatrol is correct.

Answer 6

Just like in the slope-point form of the equation for a line x1 and y1 have a lowered minus sign (-) in front of them, right?

Answer 7

yeah
