Answer:
Step-by-step explanation:
It might be B
ANSWER ………………….____________
The question is incomplete. But this explanation will help you very much.
1) Regarding the function

,
its graph always passes through the points (1,0) and (a,1).That is due to the properties of logarithm function:
a)

b)

<span>
That in turn is due to the properties of the exponential functions.
a^0 = 1 and a^1 = a
</span>
2) Regarding the y-axis.
The function

will never touch the y-axis, because the logaritm of zero is not defined. So
the graph lies to the righ of the y-axis (i.e. the domain of the function is x > 0)
5/8 is the equivalent of 40/64
Answer:
B just b
