Answer:
See below
Step-by-step explanation:
For the model function 
, 
is the vertex, and 
is the horizontal growth or shrink factor.
We know that our vertex is 
from our graph, so we'll need to determine the value of by using one of the points on the graph:
Thus, our equation for the given graph is 
.
The domain of a function is the set of all existing real x-values, thus, our domain for the given function is 
, or all real x-values.
The range of a function is the set of all existing real y-values, thus, our range for the given function is 
, or all real y-values starting with y=-1 which is included.
The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F
- Thermometer accuracy = ±2°F
- Thermometer reading = 17°F
<u>The least possible value of </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u><u> </u><u>thus</u> :
- Thermometer reading - thermometer accuracy
<u>The highest possible </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u> thus :
- Themometer reading - thermometer accuracy
Hence, the absolute value equation which represents the scenario is (17 ± 2)°F
