Question

Use synthetic substitution to evaluate the polynomial for the given value x = 1/3.
P(x) = 3x3 + 5x2 + 4x + 2
P(1/3) = ____ Enter only a number.

Answer 1

Could you not just type that into a calculator?

Answer 2

9.7

Answer 3

^ knows how to use a calculator

Answer 4

Plug in 1/3 in place of x


P(x) = 3x3 + 5x2 + 4x + 2
\[P(1/3)= 3(1/3)^3+5(1/3)^2+4(1/3)+2\]

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

got it?

Answer 9

4?
