Answer:
The answer is [tex]\frac{11}{3}[/tex].
Step-by-step explanation:
[tex]3(-\frac{2}{3} )x^{2} -2(-\frac{2}{3} )+1[/tex]
Apply rule -(-a)=a
[tex]3(-\frac{2}{3} )x^{2} -2*\frac{2}{3} +1[/tex]
[tex](-\frac{2}{3} )x^{2} =\frac{2^{2} }{3^{2} }[/tex]
[tex](-\frac{2}{3})^{2} =\frac{2^{2} }{3^{2} }[/tex]
[tex]3*\frac{2^{2} }{3^{2} }+2*\frac{2}{3} +1[/tex]
[tex]\frac{2^{2} }{3^{2} }=\frac{4}{9}[/tex]
[tex]3*\frac{4}{9} +2*\frac{2}{3} +1[/tex]
[tex]f(x)=\frac{11}{3}[/tex]
