Alex needs to revise his conjecture because the function f(x) is only greater for limited domain since it is a linear function. The function g(x) becomes greater when the value of domain is greater than or equal to 9. In such case,
$$\displaystyle{f{{\left({x}\right)}}}{>}{g{{\left({x}\right)}}}{w}{h}{e}{n}{1}\le{x}{<}{9}$$
$$\displaystyle{g{{\left({x}\right)}}}{>}{f{{\left({x}\right)}}}{w}{h}{e}{n}{x}\Rightarrow{9}$$
