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

The graph in the attached figure

Step-by-step explanation:

we have

This is a exponential function of the form

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)

using a graphing tool

The graph in the attached figure

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

a reflection across the x axis and a 90 degree rotation left and right.
