Question

For a function f(x)=b^x, if 0<b<1, the graph will always

Lots of things you can say here. One that comes to mind is "approach zero as x grows larger."

campbell_st · Answer

well the range will be  1< f(x) < b   for the given domain

The answer choices are 
A. Rise from right to left 
B.rise from left to right 
C.fall from right to left 
D.fall from left to right

Without giving away the answer, I suppose I could give a hint: the thing I said is another way of saying one of those things.

anonymous · Answer

I choose c is that correct ?

anonymous · Answer

No, you have it backwards. As x increases (moving left to right on the graph), f(x) decreases to 0 (falls).

campbell_st · Answer

the behaviour of the curve is dependent upon the value of b

is b > 1 then it rises from left to right   e.g.  y = 2^x

is b = 1 the curve is simply the line   y = 1

if  b < 1 then the curve falls from left to right... e.g.y = (0.5)^x
