Plug in 1/3 in place of x


P(x) = 3x3 + 5x2 + 4x + 2 
$$P(1/3)= 3(1/3)^3+5(1/3)^2+4(1/3)+2$$

i keep gettin the same awnser and it say i got it wrong

diyadiya · Answer

$$=3 \left(  \frac{1}{27} \right)+ 5\left( \frac{1}{9} \right)+ \frac{4}{3}+2$$
$$= \frac{1}{9}+ \frac{5}{9}+ \frac{4}{3}+2$$

diyadiya · Answer

$$\frac{6}{9}+ \frac{4}{3}+2= \frac{2}{3}+ \frac{4}{3}+2 = \frac{6}{3}+2= ?$$
I think now you can get the answer
