Answer:

f(-6) = -21

Step-by-step explanation:

Substitute x = -6 into f(x):

f(-6) = 3(-6) + (-6 ÷ 2)

       = -18 - 3

       = -21

Given :

[tex]f(x) = 3x + \frac{x}{2} [/tex]

Substituting -6 in x,

[tex]f( - 6) = 3 \times ( - 6) + \frac{ - 6}{2} [/tex]

[tex] = > f( - 6) = (- 18) + (- 3)[/tex]

[tex] = > f( - 6) = - (18 + 3)[/tex]

[tex] = > f( - 6) = - 21[/tex]

So, value of

[tex]f( - 6) = - 21[/tex]
