Ive narrowed it down to B or D, help

Answer 1

Why is B? and Why is D?

Answer 2

I've just done process of elimination so far, a log base can't be 0 or negative so that leaves me w B and D.

Answer 3

i know range is y, like up and down, and domain is x, left and right

Answer 4

yep

Answer 5

is it B?

Answer 6

Yes

Answer 7

okay why is it B

Answer 8

when graphed its in quadrant 1.. is that why D isn't true?
