How do i put in the vertex form this equation? . y=x^2 -6x+8

Y = x² - 6 x + 8 = ( x² - 6 x + 9 ) - 9 + 8 =
= ( x - 3 )² - 1 
This is the vertex form of the equation and the vertex is ( 3 , -1 ) 

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
