Replace the x by -1/2

f(-1/2) =  -2/3 * -1/2 + 5

=  1/3 + 5

= 5 1/3  or  16/3

f( - [tex]\frac{1}{2})[/tex]) = [tex]\frac{16}{3}[/tex]

substitute x = - [tex]\frac{1}{2}[/tex] into f(x)

f( - [tex]\frac{1}{2}[/tex] = - [tex]\frac{2}{3}[/tex] × - [tex]\frac{1}{2}[/tex] + 5

= [tex]\frac{1}{3}[/tex] + [tex]\frac{15}{3}[/tex] = [tex]\frac{16}{3}[/tex]
