Whats a+2 over 2=-1 ??

Not sure what exactly you meant, so i solved for both possibilities...

a=-2

assuming you mean a+2/2=-1

a+2/2=-1
simplify..
a+1=-1
subtract 1 from both sides
a=-2


a=-4

assuming you mean (a+2)/2=-1...

(a+2)/2=-1
simplify...
a/2+2/2=-1
simplify
a/2+1=-1
subtract 1 from both sides
a/2=-2
multiply both sides by 2
a=-4

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

Ithink the answer is d.
