@amistre64 can you help me?

amistre64 · Answer

your options are missing something .... they look linear but the graph is exponential

anonymous · Answer

That how it is man did you click on the link? and those are my options.

amistre64 · Answer

... no, im just guessing that the graph is exponential looking  :/

amistre64 · Answer

your options are missing a vital notation .... none of them look like "powers"

anonymous · Answer

Oh, alright /: But I do need some help...

amistre64 · Answer

notice that the graph has 2 points that can be easily determined; and it is when x=0 and another when y=0

amistre64 · Answer

one of those options has to match

anonymous · Answer

I wanted to say either A or D but hmmmmm

amistre64 · Answer

i cant tell.$$2x+4\ne2^x+4$$
$$2x+4\ne2^{x+4}$$
so i cant tell what your options really are

anonymous · Answer

I thought the same thing with the last graph. but I think the answer is f(x)=2x-4 because the graph looks like it is shifting down.
