Answer:
D
Step-by-step explanation:
Its decaying since its being multiplied by by a number less than 1
What are you looking for?
F(x + 1) = (5/2)*f(x)
f(x + 1) = 2.5*f(x), f(1) = 3.2
f(2) = 2.5f(1) = 2.5*3.2 = 8
<span>f(3) = 2.5f(2) = 2.5*8 = 20
</span>
f(4) = 2.5f(3) = 2.5*20 = 50
<span>f(5) = 2.5f(4) = 2.5*50 = 125</span>
The graph that is proportional is B because it goes through the origin and the ratio remains the same.
The Answer Is <span>factor by grouping</span>
