Problem 1

<h3>Answer: False</h3>

---------------------------------

Explanation:

The notation (f o g)(x) means f( g(x) ). Here g(x) is the inner function.

So,

f(x) = x+1

f( g(x) ) = g(x) + 1 .... replace every x with g(x)

f( g(x) ) = 6x+1 ... plug in g(x) = 6x

(f o g)(x) = 6x+1

Now let's flip things around

g(x) = 6x

g( f(x) ) = 6*( f(x) ) .... replace every x with f(x)

g( f(x) ) = 6(x+1) .... plug in f(x) = x+1

g( f(x) ) = 6x+6

(g o f)(x) = 6x+6

This shows that (f o g)(x) = (g o f)(x)  is a false equation for the given f(x) and g(x) functions.

===============================================

Problem 2

<h3>Answer: True</h3>

---------------------------------

Explanation:

Let's say that g(x) produced a number that wasn't in the domain of f(x). This would mean that f( g(x) ) would be undefined.

For example, let

f(x) = 1/(x+2)

g(x) = -2

The g(x) function will always produce the output -2 regardless of what the input x is. Feeding that -2 output into f(x) leads to 1/(x+2) = 1/(-2+2) = 1/0 which is undefined.

So it's important that the outputs of g(x) line up with the domain of f(x). Outputs of g(x) must be valid inputs of f(x).

Help me please ?!!!!

Answer:

<em>The slope of the line is -1</em>

Step-by-step explanation:

<u>Slope of a Line</u>

Suppose we know a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated as follows:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

From the table in the image, we select the points (1,4) (3,2). The slope is:

\displaystyle m=\frac{2-4}{3-1}=\frac{-2}{2}=-1

Now select two other points like (5,0) (7,-2)

\displaystyle m=\frac{-2-0}{7-5}=\frac{-2}{2}=-1

Following the same procedure with any other pair of points, we'll get the very same result:

The slope of the line is -1

Yuan has 5 quarts of broth. He uses 1/2 of the broth to make soup. Then, he uses 1/4 of the broth he has left to make gravy.
vovangra [49]

Answer:

  1 7/8 quarts

Step-by-step explanation:

The amount Yuan has left can be found by multiplying the original amount by the fraction he has left.

__

<h3>used</h3>

After using 1/2 of the broth for soup, the fraction remaining is ...

  1 -1/2 = 1/2

The amount Yuan used for gravy is 1/4 of this, or ...

  (1/4)(1/2) = 1/8 . . . of the original amount of broth

The total fraction Yuan used was ...

  fraction used = fraction for soup + fraction for broth = 1/2 +1/8 = 5/8

<h3>remaining</h3>

Then the fraction remaining is ...

  fraction remaining = 1 - fraction used = 1 - 5/8 = 3/8.

The amount remaining is this fraction of the original amount:

  (3/8)(5 quarts) = 15/8 quarts = 1 7/8 quarts . . . . remaining

A game show has a contestant pick one of five doors to reveal the prize the contestant wins. A photo of a new boat is behind one
kumpel [21]

Hi,

It is unlikely that the game show contestant will win the boat.

To be exact it is 20% chance that the game show contestant will win the boat.
