So we know that the bacteria grows 3x as much every ten minutes.  From this we know that it'll be 3 mm in 20 minute.  Continuing the pattern, we can figure out that in 40 minutes the bacteria will be 81 mm.

The pattern: 10min - 3  20min - 9  30min - 27  40min - 81

Answer:

  \begin{cases}3x+12&\text{if }x>-4\\0&\text{if }x=-4\\-3x-12&\text{if }x

Step-by-step explanation:

The absolute value function negates its argument when its argument is negative. The expression 3x+12 will be negative when ...

  3x +12 < 0

  x +4 < 0

  x < -4 . . . . . makes the absolute value function change its argument's sign

Using this fact, we can divide the domain into intervals below -4, at -4, and above -4. The above answer shows the function value in each domain interval.

Can some one please help me to teach this to my daughter
EastWind [94]
28mi/1 hr = 28 mi/60 min = 1 mi/(60/28) min = 

28 mi/hr = 28 mi/60 min since there are 60 min in 1 hr
1 mi/(60/28) min since you divide top and bottom of 28/60 by 28 to get
1 mi/(60/28) min = 1mi/(15/7) min = 1 mi/ 2 1/7 min
