Answer:

  {f(x), g(x)} = {x^4, x(x+4)}

Step-by-step explanation:

If we look at the composite function from the point of view of the Order of Operations, we see the operations performed on x are ...

  • x is squared
  • x is multiplied by 4
  • these products are added
  • the sum is raised to the fourth power

From the point of view of decomposition, we want the outer function (f(x)) to be one that can be applied to the expression produced by the inner function (g(x)). Looking at our list, we find that raising an expression to the 4th power could qualify as the outer function we want. (We could also use raising to some other power, if we wanted.)

So, f(x) = x^4.

This leaves ...

  f(g(x)) = f(4x +x^2)

so, g(x) = 4x +x^2.

One possible set of functions is ...

  {f(x), g(x)} = {x^4, x(x+4)}

Can someone help simplify?: -8x^3y2(2x^4y^4)
Kisachek [45]

So the rule with multiplying exponents of the same base is to add the exponents together. Applying this rule here would look like this:

-8x^3y^2*2x^4y^4=(-8*2)x^{3+4}y^{2+4}=-16x^7y^6

In short, your simplified expression is going to be -16x^7y^6.

Answer:

The answer is: -0.5198

Step-by-step explanation:

CUBERT(8) – CUBERT(16) is the cube root of 8 - cube root of 16:

CubeRT(8) - CubeRT(16) =

2 - 2.5198 = -0.5198
