i o n f e h y=x3- 3x2- 9 x + 2 The largest and smallest values ​​of the function [ - 2 ; 4 ]At intervals.
Oksana_A [137]

Answer:

Step-by-step explanation:

Given the function :

y=x³ - 3x² - 9x + 2. The largest and smallest values ​​of the function at interval [-2, 4]

We substitute x values in the interval (-2 to 4) into the equation and solve for y

At x = - 2

y = (-2)³ - 3(-2)² - 9(-2) + 2 = 0

At x = - 1

y = (-1)³ - 3(-1)² - 9(-1) + 2 = 7

At x = 0

y = (-0)³ - 3(-0)² - 9(-0) + 2 = 2

At x = 1

y = (1)³ - 3(1)² - 9(1) + 2 = - 9

At x = 2

y = (2)³ - 3(2)² - 9(2) + 2 = - 20

At x = 3

y = (3)³ - 3(3)² - 9(3) + 2 = - 25

At x = 4

y = (4)³ - 3(4)² - 9(4) + 2 = - 18

Function is greatest at

To Rationalize the denominator of 5-√7/9-√14, you should multiply the expression by which fractions?
beks73 [17]

<u>Answer</u>

9+√14


<u>Explanation</u>

To Rationalize the denominator of 5-√7/9-√14.

To rationalize this we multiply both the denominator and denominator by the conjugate of the denominator.

The denominator is 9-√14 and its conjugate is (9+√14).

(5-√7)/(9-√14) = (5-√7)(9+√14)/(9-√14)(9+√14)

                        =  (5-√7)(9+√14)/(9²-14)

                       = (45 + 5√14 - 9√7 - √98)/(81-14)

                        =  (45 + 5√14 - 9√7 - √98)/67

                        = (45 + 5√14 - 9√7 - 7√2)67

This is the rationalized expression.  

The denominator is (9-√14) and its conjugate is (9+√14).

I need help plz!! thx
masya89 [10]

Answer:

2nd statement describes the relation between graph of f(x) and graph of g(x).

Step-by-step explanation:  

We are told that graph of g(x)=f(x)-1 and we are asked to choose the correct statement that describes the relation between graph of f(x) and graph of g(x).

The rules for the translation are as follows:  

f(x-h)=\text{Graph shifted to right by h units}

f(x+h)=\text{ Graph shifted to left by h units}

f(x)+h=\text{ Graph shifted upward by h units}

f(x)-h=\text{ Graph shifted down by h units}    

Upon comparing our given translation with above rules we can see that our parent graph f(x) is shifted down by 1 unit to get our new graph g(x).

Therefore, graph of g(x) is the graph of f(x) translated 1 unit down and 2nd option is the right choice.

nydimaria [60]

Answer:

2.58\ more\ nuts\ Miguel\ uses\ than\ raisins.

Step-by-step explanation:

Nuts\ used=5\frac{1}{3}\\\\Nuts\ used=\frac{16}{3}

Raisins\ used=2\frac{3}{4}\\\\Raisins\ used=\frac{11}{4}

difference\ between\ nuts\ and\ raisin=\frac{16}{3}-\frac{11}{4}=\frac{64-33}{12}=\frac{31}{12}\approx 2.58

2.58\ more\ nuts\ Miguel\ uses\ than\ raisins.
