Find the domain of the function algebraically: <img src="https://tex.z-dn.net/?f=R%28x%29%3D%5Cfrac%7Bx%7D%7Bx%5E%7B2%7D

BigorU [14]

The domain of the function is all real numbers except 2 and -1

Step-by-step explanation:

Domain is the set of inputs of a function on which the function is defined.

Given function is:

$R(x) = \frac{x}{x^2-x-2}$

In case of a function involving fraction, the function is undefined if the denominator is zero so in order to find the domain of the function algebraically , we have to find the values on which the function will be undefined

$x^2-x-2 = 0\\x^2-2x+x-2 = 0\\x(x-2)+1(x-2) = 0\\(x+1)(x-2) = 0\\x+1 = 0 => x=-1\\x-2=0 = > x=2$

The function will be undefined on x=-1 and x=2

So,

The domain of the function is all real numbers except 2 and -1

What is the value of 5 2/3(−3.6)?

Anestetic [448]

Answer:

Hello, Your answer will be -20 2/4.

Step-by-step explanation:

Conversion a mixed number 5 2

to a improper fraction: 5 2/3 = 5 2

= 5 · 3 + 2

= 15 + 2

= 17

To find new numerator:

a) Multiply the whole number 5 by the denominator 3. Whole number 5 equally 5 * 3

= 15

b) Add the answer from previous step 15 to the numerator 2. New numerator is 15 + 2 = 17

c) Write previous answer (new numerator 17) over the denominator 3.

Five and two thirds is seventeen thirds

Conversion a decimal number to a fraction: -3.6 = -36

= -18

a) Write down the decimal -3.6 divided by 1: -3.6 = -3.6

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

-3.6

= -36

Note: -36

is called a decimal fraction.

c) Simplify and reduce the fraction

-36

= -18 * 2

5 * 2

= -18 * 2

5 * 2

= -18

Multiple: 17

* (-3.6) = 17 · (-18)

3 · 5

= -306

= -102 · 3

5 · 3

= -102

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-306, 15) = 3. In the next intermediate step the fraction result cannot be further simplified by cancelling.

In words - seventeen thirds multiplied by minus eighteen fifths = minus one hundred two fifths. Hope That Helps!

The domain will be the numbers you can use for x and not get a undefined thing like division by 0 or square root of a negative number

(f*g)(x)=f(x) times g(x)=(3x+2) times (7x+6)=(3x+2)(7x+6)= $21x^2+14x+18x+12=21x^2+32x+12$

the domain is all real numbers because we can't find any values of x that make a division by 0 or square root of a negative

answer is C
