Consider the curve with equation given by x4-x2y+y4=24
1. verify that the point (-2,2) lies on the curve.
2. find the equation of the line tangent to the curve at point (-2,2)
3. provide the graphs of the given curve and the tangent line together on the same xy axis.
We are given equation as
(1)
we can plug x=-2 and y=2 in left side
and check whether it is same as right side
Since, left side= right side
so,
the point (-2,2) lies on the curve
(2)
we can find derivative with respect to x
now, we can plug x=-2 and y=2
now, we can solve for y'
now, we can use point slope form of line
now, we can solve for y
............Answer
(3)
we can draw graph
