Let a function \( L(t)\) measure the amount of learning \((\mathrm{L})\) you have achieved over a certain number of hours (\( t \)) studying for a test.Answer all of the following in a manner you see fit but make sure you give proper reasoning.Which difference do you think would be larger, \( L(11)-L(10)\) or \( L(4)-L(3)\)? Additionally, do you think that the graph of \( L \) is concave up or down? Explain.Create a hand drawn sketch \( L \) as you see it.Copy and paste an image of your hand drawn sketch into the answer to support your explanation.
