Question

A scientist is studying a form of bacteria that doubles every hour. if the petri dish starts with 2 grams of bacteria

A - y=2x+2

B - y=2x^2

C - y=2x

D - y=2•2^x

Answer 1

D) -y=2*2^x

Hope this helps :)

Answer 2

b = 2x²

Explanation:

Let the number of bacteria = x

Every hour, the number of bacteria doubles itself, = x * x = x²

But the bacteria started with 2g,

The number of bacteria present is equal to

2 * x² = 2x².

At every hour, the growth of the bacteria is at 2x²
