A graph titled Position versus time for with horizontal axis time (seconds) and vertical axis position (meters). The line runs in 3 straight segments from 0 seconds 0 meters to 4 seconds 12 meters to 6 seconds 12 meters to 12 seconds 0 meters. Use the graph to determine the instantaneous speed at 2 seconds.

_m/s

What is the average speed over the entire trip?

_ m/s

Step-by-step explanation:

Use the formula:

According to the graph, the distance at 2 seconds is 6 m.

The speed is:

Total distance is 12 m and total time is 12 seconds.

The average speed is:

5.5

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
