Question

x = 1/2 (y - 1)^2 + 8
Name the vertex.

Answer 1

So (-1,8)?

Answer 2

\( \color{Black}{\Rightarrow x = a(x - h)^2 + k }\)

(h,k) is the vertex :)

Answer 3

I didn't say -h,k

Answer 4

1 will be positive in the vertex. \((1,8)\)

Answer 5

What about for an equation like -2x^2 + 3?

Answer 6

@lalaly :)

Answer 7

I didn't understand the equation...there isn't an equals sign :/

Answer 8

\( \color{Black}{\Rightarrow x = a(y - h)^2 + k }\)
*CORRECTION

Answer 9

y = -2x^2 + 3
