Evaluating Functions

f(6) if f(x) = 4x

f(5) if f(x) = 3x - 2

 $f\left(\frac{2}{9}\right)\ \$  if  $\ f\left(x\right)=3x\ +\ \frac{1}{3}$  

f(8) if f(x) = x + 11

f(-6) if f(x) = 4x + 7

 $f\left(\frac{3}{4}\right)$  if $f\left(x\right)=2x-\frac{1}{4}$  

f(3) if f(x) = 2x + 4

f(-14) if f(x) = 2x - 3

 $f\left(\frac{4}{5}\right)$  if  $f\left(x\right)=4x-\frac{1}{5}$
