very well explain sir
sir if we get foot of perpendicular we can use the mid point formula also na
in 7:55 how did you get slope of m1=-1/2
Sir, is the image : (y+2)^2 = -(x+3). Using the fact that the line containing the image is perpendicular to the mirror and will have slope 1 we can consider some point on the image and putting that back in the equation of the parabola given to get the image.

Yes, correct. Very good.
let the equation of parabola is x=ay^2+by+C assume some point on given parabola find its image and pit it in the equation the find the value of a b c

I believe this won't be the correcr method. 3 variables.
