How did America’s far-flung international responsibilities shape the U. S. economy and society in the Eisenhower era? Was the American way of life fundamentally altered by the nation’s new superpower status, or did it remain largely sheltered from world affairs?

You're asking in the ap section, so i'll give the ap calculus-style answer. alternatively, you can find the vertex of the parabola and use the "y"-coordinate as the answer.

the maximum height can occur at a critical number, that is, a number  such that  .

the derivative of  can be calculated as follows:



find a value of  that is a zero of the derivative:


this is parabola that is opening downward; we can assume there is a maximum at  .

to find that maximum, calculate  .
