Convert y=x2 + 4x + 3 from standard form to vertex form

Hello : 
x²+4x+3 = x²+2(2x)+4-4+3
              = (x²+2(2x)+2²) -1
x²+4x+3 = (x+2)² -1 (vertex form )    the vertex is : A( -2 ; -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
