Are the functions commutative or not commutative.
Blizzard [7]

Answer:

  1. commutative
  2. not commutative

Step-by-step explanation:

1. The functions in a composition will be commutative if they are inverses of each other.

  f(g(x)) = 1/4(4x-20) +5 = x -5 +5 = x

  g(f(x)) = 4(1/4x +5) -20 = x +20 -20 = x

The functions f and g are inverses of each other and are commutative. Application of these functions in either order will give the same result--the original function's argument.

__

2. f(g(x)) = 2(x^2 -3) +4 = 2x^2 -2

   g(f(x)) = (2x +4)^2 -3 = 4x^2 +16x +13

f(g(x)) gives a different result than g(f(x)), so the functions are not commutative.

3) Tommy is drawing a triangle with angles measuring 41° and 123°, and the included side measures 6 cm. What is the measure of t
zvonat [6]
The answer I believe would be "D", the full shape of the triangle should add up to a total of 360 degrees, so adding "123" and "41" comes out to "164" So then you would just see which of the options would add up to 360.
