The graph of g(x) is shown. On a coordinate plane, a piecewise function has 2 lines. The first line has a closed circle at (negative 4, 4) and goes down to a closed circle at (negative 1, 1). The second line has a closed circle at (0, 1) and goes do to an open circle at (3, negative 1). Which statements describe the domain and range of g(x)? Select two options. The function g(x) is defined for all real numbers x. The maximum value of the range is 4. The maximum value of the domain is 3. The range of g(x) is {y| –1 < y ≤ 4}. The domain of g(x) is {x| –4 < x ≤ 3}.

The maximum value of range is 4

The range of g(x) is y|-1 < y < 4

Step-by-step explanation:

- "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."
