Noah spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -13°F. Between 9am and noon, the temperature increased by 6.3°F. Between noon and 3pm, the temperature rose 3.9°F. Between 3pm and 6pm, the temperature decreased by 16.1°F. What was the temperature at 6pm?

-18.9 °F

Step-by-step explanation:

First, find the temperature at noon:

-13 + 6.3

= -6.7

Then, find the temperature at 3pm:

-6.7 + 3.9

= -2.8

Then, find the temperature at 6pm:

-2.8 - 16.1

= -18.9

So, the temperature at 6pm was -18.9 °F

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
