Answer:
A. f(25) = 15
Step-by-step explanation:
there are three functions given,
1st.
3√x .............replace x with 25 cause f(25)
3√25
3*5
15 ......given that x≥9, so 15 falls above 9 and is correct
2nd.
-| 2x |
-| 2(25) | .....replace x here as well
- |50|
-50 .......given that 0<x<9, but it doesn't fall between 0 and 9 so wrong.
3rd.
13 .......given x≤0, 13 doesn't fall under or equal to 0 but is above so wrong.
Therefore can be concluded answer is 15
