Question

What is the vertex of the parabola x = 5(y – 4)2 – 1 ?

Answer 1

Please anyone, help. I know that the cordnites to the a vertex is (h,k) with : y = a(x – h)2 + k being the equation...

Answer 2

Youre correct. SO since you know (h,k) is the vertex, apply that to your problem. Try to get your equation to be y=?

Answer 3

It's sqrt((x+1)/5)+4 = y
However, that doesn't fit with the (h,k) then

Answer 4

gimme a sec plz

Answer 5

since this is a "sidways" parabola, then your vertex is (k, h)

Answer 6

So, (-1,4)?
