Q:
Given f(x)=2x2−5x−3 and g(x)=2x2+x .What is (fg)(x) ?−2x−3x where x≠0, −12x−3x where x≠0, −12x−2x−3 where x≠0, −32xx−3 where x≠0, 3
Accepted Solution
A:
Answer:For (fg)(x)(fg) (x) = 4x^4 - 8x^3 -11x^2 -3xWith no restrictions on the xStep-by-step explanation:To find (fg) (x) = f(x) . g(x) We need to multiply f(x) with g(x) (fg) (x) = (2x^2 -5x -3) * (2x^2 + x)fg(x) = 4x^4 + 2x^3 - 10x^3 - 5x^2 -6x^2 -3xfg(x) = 4x^4 - 8x^3 -11x^2 -3x
