Suppose that at time $t_0$ we have x mold cells. We are told that after 12 minutes the amount present is double. That is a $t= t_0+12$ we have 2x cells. Then, at $t = t_0+24$ we have (2x)*2 = 4x. We can continue as follows

$t: t_0+36$ we have (4x)*2 = 8x.

$t: t_0+48$ we have (8x)*2 = 16x

$t: t_0+60$ (one hour later) we have (16x)*2 = 32x.

So after one hour from now we have 32x cells.

What is the average rate of change of the function f(X)= 2x - 1

blondinia [14]

Answer:

Step-by-step explanation:

The average rate of change of the function f(x) is

$\dfrac{f(b)-f(a)}{b-a}$

1. At $a=1,$

$f(1)=2\cdot 1-1=1$

2. At $b=2,$

$f(2)=2\cdot 2-1$

The average rate of change is

$\dfrac{3-1}{2-1}=\dfrac{2}{1}=2$
