Given the following functions f(x) and g(x), solve (f ⋅ g)(3) and select the correct answer below:
amm1812
(f * g)
(4x^2 + 12)(x - 1) = x(4x^2 + 12) - 1(4x^2 + 12) = 4x^3 + 12x - 4x^2 - 12 =
4x^3 - 4x^2 + 12x - 12

(f*g)(3) = 4(3^3) - 4(3^2) + 12(3) - 12 = 4(27) -4(9) + 36 - 12 =
108 - 36 + 36 - 12 =

Is 6x 2/8 the same as 6 x 1/8?
Pachacha [2.7K]
No
6×\frac{2}{8}=\frac{3}{2} or 1.5
More: 6×\frac{1}{4}=3×\frac{1}{2}=\frac{3}{2}
6×\frac{1}{8}=\frac{x3}{4} or 0.75
More: 3×\frac{1}{4}=\frac{3}{4}
Both are different.
