the function is positive, so do you know the general shape of this function?
OpenStudy (anonymous):
no :/

if not, just plot a few points to see the general shape of your equation. This should be the easiest way to see the answer
OpenStudy (anonymous):
for example, try plugging in x = 1 or something to figure out what coordinates you should have, then compare it with these graphs to see which one is right
OpenStudy (anonymous):
A
OpenStudy (anonymous):
nope, if you plug in 1 for x, you get a positive Y
The graph doesn't show that...

D correct
OpenStudy (anonymous):
yup :)

yayy! :D

same thing, just test a few points to see which one fits

test it at x=0, to see what your y is. That should already eliminate two answers
OpenStudy (anonymous):
Then test at some other points

should be a

and btw, are you using a graphing software? If it's the case, then you should really try it without... It'll help you understand these things better
OpenStudy (anonymous):
just do like I said, just test and plot a few points to see if it correspond to the graph, if not then reject that answer.
Work by elimination till you get the only one graph that works
