Answer:

f(6) = 51

Step-by-step explanation:

f(x)= x² + 3x - x/2

In order to find f(6) ,we need to substitute

x by 6 in the expression of f :

f(6) = (6)² + 3(6) - (6)/2

    = 36 + 18 - 3

    = 54 - 3

    = 51

Then

f(6) = 51

Answer:

f(6) = 51

Step-by-step explanation:

Simplify:

  Substitute the value of x

[tex]\sf f(x) =x^2 + 3x -\dfrac{x}{2}\\\\f(6)=6^2 + 3*6 -\dfrac{6}{2}\\\\[/tex]

        = 36 + 18 - 3

        =  51
