f(-3) = (2*(-3)*(-3) - 5) / (4*(-3)*(-3)+3) = 1/3

 

f(-3/2) = (2*(-3/2)*(-3/2) - 5) / (4*(-3/2)*(-3/2)+3) =  - 1 / 24

 

f(0) = (2*(0)*(0) - 5) / (4*(0)*(0)+3) = -5/3

 

f(1) = (2*(1)*(1) - 5) / (4*(1)*(1)+3) = -3/7

 

f(2/3) = (2*(2/3)*(2/3) - 5) / (4*(2/3)*(2/3)+3) = (-37/9) / (43/9) = -37/43

 

f(3) = (2*(3)*(3) - 5) / (4*(3)*(3)+3) = 1/3
