The  knowledge gap  as been recast more recently as a “digital divide”  gap. with the internet and social media many things can be done faster and better. so much faster and better that those that do not have access to them are literally left out of the game. 

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  .
