The square root of the cube root of x can be expressed as
42 . C
The point where the horizontal line and the parabola intersect must be
the vertex of the parabola. In order to find the point of intersection, set
the equations equal to each other.
Since x = 5 and the vertex is on the line y = −1, the coordinates of the
vertex are (5, −1).
