Question

Don't understand letter K can u write the equation of the described function in standard form

Answer 1

The general or standard form of a parabola is

(y-k) = a(x+h)^2

h,k are the intersection points of parabola

Intersection points are where y= 0, or x=0

itsnorigin at (,0,0)that means h=0, k=0

it passes through points (-1,2) and (1,2)

So then

y= ax^2 , 2 = a (-1)^2

this means a= 2

Then results standard form equation

Y = 2• X^2
