Option a. 11 is the right answer
Step-by-step explanation:
To find the value of a function on particular input, the value is put in the function in place of variable
Given function is:
[tex]f(x) = \left \{ {{3x-7\ \ \ x>0} \atop {2x+3\ \ \ x<0}} \right.[/tex]
As we have to find f(6) and x>0 the part of function 3x-7 will be used
so,
[tex]f(6) = 3(6)-7\\= 18-7\\=11[/tex]
Hence,
Option a. 11 is the right answer
