spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -8.8°F. Between 9am and noon, the temperature increased by 13.6°F. Between noon and 3pm, the temperature decreased by 6.9°F. Between 3pm and 6pm, the temperature went down 2.1°F. What was the temperature at 6pm?

4

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
