Step-by-step explanation:
Answer:

Step-by-step explanation:
The parent log function has a vertical asymptote at x=0, so the asymptote at x=-3 indicates a left shift of 3 units.
The parent log function crosses the x-axis 1 unit to the right of the vertical asymptote, which this one does, indicating there is no vertical shift.
The parent log function has an x-value equal to its base when it has a y-value of 1. Here, the y-value of 1 corresponds to an x-value 3 units to the right of the vertical asymptote, so the base of this logarithm is 3.
The function is ...

This is an arithmetic sequence.
d= 0.5-3=-2.5
d= - 2.5
a(1)= 13
a(n) = a(1) +d(n-1)
a(n)=13-2.5(n-1)=13-2.5n+2.5= 15.5 - 2.5n
a(n)= 15.5 - 2.5n
Answer C. a(n)= 15.5 - 2.5n
