Find the point on the curve y=4x+4 closest to the point (0,8)
(x,y)=
we have
...................1)
and
the distance formula is,
put the value of x1 = x, x2 = 0
y1 = y = 4x + 4 and y2 = 8,
here d is as small as possible value hence we can write new set D,
for the minimum value
put this value in equation 1),
hence
so the point on curve y which is closest to (0, 8) is,
