Please answer asap! show work! 11. What is (f.g)(x)? f(x) = x3 +3 g(x) = 2x2 + x - 1

Ksenya-84 [330]

Answer:

2x⁵ + x⁴ - x³ + 6x² + 3x - 3

Step-by-step explanation:

Given :

f(x) = x³ + 3
g(x) = 2x² + x - 1

Finding (f × g)(x) :

f(x) × g(x)
(x³ + 3)(2x² + x - 1)
2x⁵ + 6x² + x⁴ + 3x - x³ - 3
2x⁵ + x⁴ - x³ + 6x² + 3x - 3

pav-90 [236]

If you plug in 7 for n, you get
(7+1)(7-2).
Simplify that.
(8)(5)
Simplify that and you get the 7th term of the particular sequence is,
