What is the average rate of change for this quadratic function for the interval from
x = 2 to x = 4?

Hence,the average rate of change for this quadratic function for the interval from x = 0 to x = 2 is:

-2

Step-by-step explanation:

The average rate of a function f(x)  from x=a to x=b is given as:

Clearly we are asked to find the average rate of change from x=0 to x=2.

i.e. a=0 and b=2

Also, from the graph it could be observed that:

f(0)=1

and f(2)=-3

Hence, the average rate of change is calculated as:

Hence,the average rate of change for this quadratic function for the interval from x = 0 to x = 2 is:

-2

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
