Answer: $3x^{2}-24x$

Step-by-step explanation:

1. To simplify the expression given in the problem, you must apply a property of exponents called Quotient of powers, which states that when you divide two powers that have the same base, you must subtract the exponents.

2. Keeping this property on mind you have, you can rewrite the expression as following and simplify:

$\frac{-12x^{4}}{-4x}+\frac{96x^{2}}{-4x}=3x^{2}-24x$

(f.g)(x) = f (g(x))= f ( x^4+3)

= (x^4+3)^2 + 2 ( x^4+3) - 6

= x^8 + 9 + 6x^4 + 2x^4 + 6-6

= x^8 + 8x^4+9

The function f(x) is shown below.

Elenna [48]

The value of f(g(2)) is 2.

<h3>What is function?</h3>

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The given table is

x f(x)

If the coordinates of a function f(x) is defined as (x,y)

then, the coordinates of inverse of f(x) is defined as (y,x).

f(g(y))= f(x) [ g(x)= (y,x)]

f(g(y))= y

So, If g(x) is the inverse of f(x), the f(g(y)) = y.

Also, we know g(x) is the inverse of f(x), then f(g(2)) = 2.
