We don't know if this is an inflection point, is this a maximum, is this a minimum? So really we just want to evaluate g at this point to see if it gets higher than when we evaluate g at 3. So let's evaluate g at 5 halves. So g at 5 halves is going to be equal to 2 times 5 halves plus the integral from 0 to 5 halves of f of t dt. So this first part right over here, the 2's cancel out, so this is going to be equal to 5, and then plus the integral from 0 to 5 halves. Now, you might be able to do it visually, but we know what the value is of f of t over this interval. We already figured out the equation for it over this interval.
