Step-by-step explanation:
Domain of a function is defined by the set of x-values of the graph of a function.
From the graph attached,
x-values are starting from x > 0 [Since x ≠ 0] and moves towards infinity,
Therefore, domain of the function will be,
(0, ∞) Or x > 0
Form the ratio 560/2800 and then mult. the result by 100%:
560
--------- * 100% = 20%
2800
That answer will be 30 songs.
In order to get that answer you must multiply 40 by 18 which is 720 and divide it by 24 . Finally you get the answer 30 songs.
