Answer 2

that is not the correct graph for that function (according to Desmos...)

Answer 3

this is the one on my test though

Answer 4

oh my bad its y= ( 2^x-2^-x)/2

Answer 5

OK - so what is the problem

You have the graph - it asks you how many 'zeroes' there are.

That means y=0

the graph is y=0 when it crosses the x axis

how many times does it do that?

Answer 6

once?
