CAC can be changed into CAAC. This is because the first rule says that any letter can change into an A so
CAC=CAA
The last condition says that when you double , you have to double all letters,
Since A has been doubled,C needs to be doubled too.So:
CAA=CAAC

Which graph represents the function?

Setler79 [48]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

1) $f(x)=(x+2)^2$ -----> For the interval (-∞,-1)

Note The value of x=-1 is a open circle ( is not included)

This is a vertical parabola open upward

The vertex is a minimum

The vertex is the point (-2,0)

2) $f\left(x\right)=\left|x\right|+1$ ----> For the interval [-1,1]

Note The value of x=-1 and x=1 are closed circle ( both values are included)

This is an absolute function open upward

The vertex is the point (0,1)

3) $f(x)=-\sqrt{x}$ -----> For the interval (1,∞)

Note The value of x=1 is a open circle ( is not included)

The value of f(x) is negative for all values of x

therefore

The graph in the attached figure

Arturiano [62]

Answer:

6x^2 - 10x - 24

Step-by-step explanation:

Do 3x times 2x which is 6x^2
Do 3x times - 6 which is -18x
Do 4 times 2x which is 8x
Do 4 times - 6 which is - 24
You get 6x^2 - 18x + 8x - 24
