So four minus x times log of nine. Four times log of nine. And this looks like some type of a logarithm expression at first until you realize that log of nine is just a constant. Log base 10 of nine, it's gonna be some number close to one. This is just, this expression would actually define a line. For x greater than or equal to three, g of x is just a line, even though it looks a little bit complicated. And so this is actually defined for all real numbers.
