Answer:

The correct answer is distributive postulate.

Step-by-step explanation:

Look at the expression we have given:

3x + 3 = 3(x + 1)

And we are asked that which postulate is illustrated for the real numbers.

We know that the distributive property of multiplication states that we can multiply a sum of numbers by multiplying each addend separately and finally add the products.

a*(b+c)= a*b+a*c

where a,b and c are real numbers.

3(x+1)= 3*x+3*1 = 3x+3

Therefore the correct option is distributive postulate....

Select the correct answer. which equation could possibly represent the graphed function?

MakcuM [25]

The function for the given graph is f(x) = (x - 4)(x + 2)(x + 4).

<h3>How to represent a graph by an equation?</h3>

A graph can be represented by the equation y = f(x).
In the equation, the variable x is called the independent variable and the variable y is called the dependent variable.

<h3>Calculation:</h3>

In the given graph,

The points that lie on the x-axis are (-4, 0), (-2, 0), and (4, 0) where y-coordinate is 0 and the x coordinates are -4, -2, and 4.

On solving the given functions,

Option A:

f(x) = (x - 4)(x + 2)(x + 4)

Since y = 0 consider f(x) becomes 0

So,

(x - 4)(x + 2)(x + 4) = 0

According to the zero product rule,

x - 4 = 0, x + 2 = 0, and x + 4 = 0

⇒ x = 4, x = -2 and x = -4.
