Question

b) select the option that best describes the meaning of ( p(1.8) ).
after 1.8 hours of working, skylar will have earned ( p(1.8) ) dollars that day.
after 1.8 hours of working, skylar will be earning ( p(1.8) ) dollars per hour.
after ( p(1.8) ) hours of working, skylar will have earned 1.8 dollars that day.
none of these describe the meaning of ( p(1.8) ).

Explanation:

Step1: Analyze function notation

In the function \(P(x)\), \(x\) is the input (independent variable) and \(P(x)\) is the output (dependent variable). Here, \(x\) represents the number of hours worked.

Step2: Interpret \(P(1.8)\)

When \(x = 1.8\) (1.8 hours of working), \(P(1.8)\) represents the total amount of money earned (since the \(y -\)axis likely represents earnings).

Answer:

After 1.8 hours of working, Skylar will have earned \(P(1.8)\) dollars that day.
