The amount of algae in a fish tank doubles every day. Initially, the tank has 20 grams of algae in it so that the function Y=20(2^x) models the amount of algae in the bowl after x days. Which graph represents this function

Respuesta :

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

[tex]y=20(2)^{x}[/tex]

This is a exponential function of the form

[tex]y=a(b)^{x}[/tex]

where

a is the initial value

b is the base

In this problem

a=20 g

b=2

Remember that

b=1+r

so

1+r=2

r=2-1=1

r=100% (the amount of algae in a fish tank doubles every day)
