Answer :
- We change the unknown "x" for the value obtained (in this case "-6").
[tex]f( - 6) \: = \: ( - \frac{3}{2} ) \times \: ( - 6) \: + \: 10[/tex]
[tex]f( - 6) \: = \: 3 \: \times \: 3 \: + \: 10[/tex]
[tex]f( - 6) \: = \: 9 \: + \: 10[/tex]
[tex]f( - 6) \: = \: \boxed{ \bold{19}}[/tex]
Answer:
[tex] \boxed{ \bold{19}}[/tex]
