The tangent to the ellipse 3x2+16y2=12, at the point (1, 3/4), intersects the curve y2+x=0 at :
no point
exactly one point
two distinct points
more than two points
Tangent at 1,34 to the ellipse 3x2+16y2=12 is
x⋅14+y3434=1⇒x+4y=4
which intersects the curve y2+x=0 at points for which
y2+(4−4y)=0⇒(y−2)2=0⇒y=2
and the points of intersection is (– 4, 2) exactly one point.
