Answer:
y=-3log(3)(x+3)
Explanation:
because the vertical asymptote at x=-3, the graph shifted to the left 3 units from x=0
y=A.log base(b)(x+3)
the graph passes through 2 points (-2,0) and (1,-3)
A=-2, b=0 and see if it fit point(0,-3)
-3 =-2log(0)(0+3) it is undefined check both sides if equal / not equal
check point (1,-3) ( shifted left 3 points)
A=-3, b=3
-3=-3log(3)(3) it is right
y=-3log(3)(x+3)
i hope it is right
