Find the maximum revenue for the revenue function

Question

R(x) = 383x − 0.6x2.

Answer 1

Find the vertex of the parabola by first finding the x-value of the vertex by -b/2a

Then plug the x-value you got back into the original function R(x)

The y-value of the vertex is the max. revenue

Answer 2

R(x) = 355x − 0.6x2.
