So let's say that we want to find the indefinite, or we want to find the definite integral going from negative one to three of seven x squared dx. What is this going to be equal to? Well, what we want to do is evaluate what is the antiderivative of this? Or you could say, if this is lowercase f of x, what is capital F of x? Well, the reverse power rule, we increase this exponent by one. So we're going to have seven times x to the third and then we divide by that increased exponent. So seven x to the third divided by three.
