Answer:
a)
c)
d)
Explanation:
a) true : from inspection of the graph, when h=0, g=50, so g(0)=50
b) false : we are told that h is hours after 8:00am. Therefore, when h=12, this would be 8:00pm
c) true : from inspection of the graph, the maximum temperature occurs when h=7. We are told that h is hours after 8:00am, so when h=7 this would be 15:00 = 3.00pm
d) true : from inspection of the graph, we can see that when h=11, g≈62 and when h=8, g≈74. Therefore g(11) < g(8)
e) false : at 8.00am, h=0 and g=50. At 1.00pm, h=5 and g≈71. 71-50=21. 21≠10.
