Its either b or d

anonymous · Answer

ok thanks to be sure ill ask @wio

@PinkSapphire

anonymous · Answer

Well, first let x = 0  and solve for y,  then let y = 0 and solve for x.  What do you get?

anonymous · Answer

Doesn't x=3/2

0=-2x+3

2x=3

x=3/2

y=-2(0)+3

y=3

Is this right wio?

anonymous · Answer

Aha, so it would be b, since they both intersect at 1.5.
...
I would confirm with wio first.

anonymous · Answer

Yes.

pinksapphire · Answer

Yes B is correct.

anonymous · Answer

We know that it has points $(3/2,0)$ and $(0,3)$, but since we are also drawing the inverse we should have points $(0,3/2)$ and $(3,0)$ as well.

anonymous · Answer

And B is the only one going through all these points.

anonymous · Answer

Did I pass? lol.

anonymous · Answer

But you didn't ask the question, did you?

anonymous · Answer

Sorry... I kinda hyjacked your prey.

ranga · Answer

Another quick way to find the answer is a plot of f(x) and its inverse will be symmetric about the y = x line.  That is, symmetric about a 45 degree line passing through the origin.  There is only one answer choice that is symmetric about y = x line.
