If is an antiderivative of , then the area under the curve between x = a and x = b is given by . In other words, evaluate an antiderivative of your function, evaluate it at x = b and x = a, and then evaluate the difference between these values.
Hello, I'm a freshman in highschool trying to get a headstart into calculus, so please excuse my limited knowledge in the subject.
Anyways, I have this integral
I have some sort of idea on how to solve it. Something about taking the anti-derivative.
The answer is 3, but I would like to know how to get there step by step, I'm having a hard time comprehending my calculus book.
