The temperature in Fairbanks, Alaska begins at -2ºF and gets 3 degrees warmer each hour. Temperatures in Juneau, Alaska are modeled in the graph shown. image Which statement BEST describes the two situations? A. Fairbanks has a lesser rate of change and a lesser initial value.
B. Fairbanks has a lesser rate of change and a greater initial value. C.Fairbanks has a greater rate of change and a greater initial value.
D. Fairbanks has a greater rate of change and a lesser initial value.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

(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.

what is the question?
