Answer:

(b) f(x) = 5(2/5)^x

Step-by-step explanation:

All of the offered choices agree that the multiplier of the exponential factor is 5. When x=1, the exponential factor must have a value of 2/5 in order to make the function value be 2 at that point.

That is, ...

f(1) = 5(2/5)^1 = 5(2/5) = 2

You can get there either by using x=1 in each of the offered answer choices, or by observing that the ratio between f(1) and f(0) is 2/5.

f(x) = 5(2/5)^x

Find the slope.<br> (if it's a fraction with a whole number, write it as an improper fraction)

tiny-mole [99]

As you can see, every time x increases by 2, y decreases by 5.

So, we have

$m=\dfrac{\Delta y}{\Delta x}=\dfrac{-5}{2}=-2\dfrac{1}{2}$
