Question

value of polynomial f(x) = 3x^2-x+4,at x=3​

Answer 1

Answer:

For what value of k, is the polynomial f(x) = 3x4 – 9x3 + x2 + 15x + k completely divisible by 3x2 – 5 ? Answer. k + 10 = 0. ⇒ k = –10. Related

Answer 2

Step-by-step explanation:

$\rm \: f(x) =3x^2-x +4, at \: x=3$

Having x = 3 values,

$\rm \: f(3) =3(3)^{2-3} +4$

$\rm \: f(3) =3(3)^{ - 1} +4$

$\rm \: f(3) = \frac{ \cancel3}{ \cancel3} +4$

$\rm \: f(3) = 1 +4$

$\rm \: f(3) = 5$
