x - 4 = 4

3x = 24

Start Fraction x Over 8 End Fraction = 1

Step-by-step explanation:

x + 2 = 10; 8 + 2 = 10

x - 4 = 4; 8 - 4 = 4

3x = 24; 3(8) = 24

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 =

Answer:

$\large\boxed{x\in\mathbb{R}-\{1\}}\to\text{any real number except 1}$

Step-by-step explanation:

$\dfrac{x-1}{x-1}=1\\\\\text{Domain:}\ x-1\neq0\qquad\text{add 1 to both sides}\\\\x\neq1\\\\\text{We know:}\ \dfrac{a}{a}=1\ \text{for any real number except 0}.\\\\\text{Therefore}\ x\ \text{is any real number except 1}.$
