And the easiest value to try out would just be 1. So let's try out x equals 1. It's in that interval. So when x equals 1, I'll just write g prime of 1 is equal to 4 minus 5, which is equal to negative 1. So g prime of x is less than zero. g prime of x is less than zero. So our function, so we could say g is increasing here, it is decreasing, oh sorry, let me be careful.
