Determine the domain and range of the function f (x) = 2 RootIndex 3 StartRoot 108 EndRoot Superscript 2 x. A: {x| all real numbers}; {y| y > 0}
B: {x| all real numbers}; {y| y ≥ 0}
C:{x| x > 0}; {y| all real numbers}
D: {x| x ≥ 0}; {y| all real numbers}

The correct answer is A  {x/ all real numbers}; {y/ y> 0}

Step-by-step explanation:

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
