Determine if x+3 is a factor of -3x^3+6x^2+6x+9. How do u know

1 answer:

6 0

By the factor theorem, if x + 3 is a factor of f(x) = -3x^3 + 6x^2 + 6x + 9, then f(-3) = 0
f(-3) = -3(-3)^3 + 6(-3)^2 + 6(-3) + 9 = -3(-27) + 6(9) - 18 + 9 = 81 + 54 - 9 = 126.

Therefore, x + 3 is not a factor of the given function

U need help ASP .<br>f(x)=1-3X and g (x)=x+4 calculate gf(-2)<br>

IgorC [24]

Answer:

gf (-2) = 11

Step-by-step explanation:

$f(x) = 1 - 3x \\ g(x) = x + 4 \\ gf( - 2) = ..$

$gf = .. \\ g(1 - 3x) \\ = 1 - 3x + 4 \\ = - 3x + 5 \\ gf = - 3x + 5$

$gf( - 2) = - 3( - 2) + 5 \\ = 6 + 5 = 11$
