Answer:

<h2>f(19) =  -  \frac{27}{7}  \\</h2>

Step-by-step explanation:

f(x) =  \frac{3}{x + 2}  -  \sqrt{x - 3}  \\

To find f(19) , substitute the value of x that's 19 into f(x). That is for every x in f (x) replace it with 19

We have

f(19) =  \frac{3}{19 + 2}  -  \sqrt{19  - 3}  \\  =  \frac{3}{21}  -  \sqrt{16}  \\  =   \frac{1}{7}  - 4 =  \frac{1 - 28}{7}

We have the final answer as

f(19) =  -  \frac{27}{7}  \\

Hope this helps you

According to the Rational Root Theorem, which function has the same set of potential rational roots as the function g(x) = 3x5 –
elena55 [62]

Answer:


Step-by-step explanation:

Given is an algebraic polynomial of degree 5.

g(x) = 3x^5-2x^4+9x^3-x^2+12\\

Here leading term is p=3 and constant term is q =12

Factors of p are ±1,±2,±3

Factors of q are \frac{±1,±2,±3,±4,±6,±12} \\

Possible forms of p/q will be the same for any other polynomial of degree 5 with leading term =3 and constant term = 12

Hence any other polynomial

g(x) = 3x^5+ax^4+bx^3+cx^2+12

will have same possible zeroes of p/q, when a,b,c are rational.

Hence any polynomial of this type would have the same possible rational roots.

Answer:

( 1, -3 )

Step-by-step explanation:

6x - 9 = y \\ y =  - 3x \\  \\ 6x - 9 =  - 3x \\ 6x + 3x = 9 \\ 9x = 9 \\ x = 1 \\  \\ y =  - 3x \\ y =  - 3(1) \\ y =  - 3

Mashutka [201]

Answer:

6x2 + 150 = 0

12x + 150 = 0

12x + 150 = 0

-150         -150

 12x  =   -150

12x ÷ 12  = -150 ÷ 12

x= -25/2

F(x) = x2 + 10<br> What is the average rate of chan<br> hange of f over the interval [-2, -1]?
Readme [11.4K]

The average rate of change is given by [f(b) - f(a)]/(b - a), where a and b represent the interval [a, b].

Let a = -2

Let b = -1

[(-1)^2 + 10 - ((-2)^2 + 10)]/(-1 -(-2))

[1 + 10 - (4 + 10)]/(-1 + 2)

[1 + 10 -4 -10]/(1)

[1 - 4]/(1)

-3/1

Answer: -3
