Write a program in Visual Basic for Excel that provides thedetails
of a parabolic function, including a plot in Excel. A parabolic
function has thefollowingform:
y=ax2+bx+c
The results should be as follows:
a) Indicate is the equation has real solution.
Hint: compute thediscriminant of the equation and check if it is
positive orzero.

b) If the equation has complex roots finish the program and
provide a message to the user indicating that there are no
real roots for this equation.
c) For real roots indicate if the parabola is concave orconvex.
Hint:Determine if the a>0 or a

d) Determine the vertex of the parabola
Hint: The vertex is a maximum for a convex parabola and a minimumfor a
concave parabola. The x-coordinate of the vertex is given by:
x=-b/2a
