This means that the curve has a turning point at x=0 simultaneously y = 4 at that point.
As x reaches infinity y reaches infinity concluding that this curve is has a minimum at (0,4) expands towards y's positive direction.
Therefore, a tangent or a normal could be drawn at (0,4) not at the origin.
And as it is easy to figure out, the tangent drawn at (0,4) has a gradient of 0 (according to the derivative at x=0) hence the tangent is parallel to x axis. Since y=4 at x=0, line parallel to x axis at this point is y=4
Again any normal to the x axis is parallel to the y axis hence at that point, the normal is x=0 turning out to be again the y axis.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
