Question

Pleaseee help me solve this

Answer 1

51

Explanation:

`f(x)=x^(2)+3x-(x)/(2)`

The question is to find F(6), so just replace the x variable with 6, like this

`f(6)=6^(2)+3(6)-(6)/(2)`

Now simplify

`f(6)=36+18-3\\f(6)= 51`

Answer 2

f(x)=x² +3x-x/2

f(6)=(6)²+3(6)-6/2

= 36 + 18 -3

=51
