Answer:

(3x^2+1)*(7x-2)

Step-by-step explanation:

(1): "x2"   was replaced by   "x^2".  1 more similar replacement(s).

STEP

1

:

Equation at the end of step 1

 (((21 • (x3)) -  (2•3x2)) +  7x) -  2

STEP

2

:

Equation at the end of step

2

:

 (((3•7x3) -  (2•3x2)) +  7x) -  2

STEP

3

:

Checking for a perfect cube

3.1    21x3-6x2+7x-2  is not a perfect cube

Trying to factor by pulling out :

3.2      Factoring:  21x3-6x2+7x-2

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  7x-2

Group 2:  21x3-6x2

Pull out from each group separately :

Group 1:   (7x-2) • (1)

Group 2:   (7x-2) • (3x2)

              -------------------

Add up the two groups :

              (7x-2)  •  (3x2+1)

20*5= 100

100-91.25=8.75

8.75/5= $1.75

Suppose f(x)=2^x. What is the graph of g(x)=1/3f(x)?
svetlana [45]

Please see the <em>blue</em> curve of the image attached below to know the graph of the function g(x) = (1/3) · 2ˣ.

<h3>How to graph a transformed function</h3>

Herein we have an <em>original</em> function f(x). The <em>transformed</em> function g(x) is the result of <em>compressing</em> f(x) by 1/3. Then, we find that g(x) = (1/3) · 2ˣ. Lastly, we graph both function on a <em>Cartesian</em> plane with the help of a <em>graphing</em> tool.

The result is attached below. Please notice that the <em>original</em> function f(x) is represented by the red curve, while the <em>transformed</em> function g(x) is represented by the blue curve.
