Suppose that $g(x)=f^{-1}(x)$. If $g(-15)=0$, $g(0)=3$, $g(3)=9$ and $g(9)=20$, what is $f(f(9))$?
never [62]

Answer:

0

Step-by-step explanation:

\text{If } g(x)=f^{-1}(x);$ and:$\\g(-15)=0,$  g(0)=3,  g(3)=9,  g(9)=20

We are to determine the value of f(f(9)).

Now:

g(0)=f^{-1}(0)=3\\g(3)=f^{-1}(3)=9

From:

g(3)=f^{-1}(3)=9\\f(9)=3

From:

g(0)=f^{-1}(0)=3\\f(3)=0

Therefore:

f(f(9))=f(3)=0

What is the remainder when x^3 - 1 is divided by (x + 2)?
Semenov [28]

Answer:

-9

Step-by-step explanation:

Use synthetic division here.  The divisor will be -2, which comes from the divisor (x + 2):

-2    /      1    0    0    -1

                   -2    4    -8

       -------------------------

              1      -2   4    -9

The remainder is -9.

Use any method to multiply (3a + 2b – c)(a – b + 2c).
umka21 [38]

Answer:

A)

3a2 – 2b2 – 2c2 – ab + 5ac + 5bc

(3a + 2b - c)(a - b + 2c) \\  = (3 {a}^{2}  - 3ab + 6ac + 2ab - 2 {b}^{2}  + 6bc - ac + bc - 2 {c}^{2} ) \\  = 3 {a}^{2}  - ab + 5ac - 2 {b}^{2}  + 5bc -  {2c}^{2}  \\  = 3 {a}^{2}  - 2 {b}^{2}  -  {2c}^{2}  - ab + 5ac + 5bc

dem82 [27]
The domain of a certain function are all possible values of x that are applicable to the function or can make the function true. For this certain function, the domain is from the time that the book was released to the time that the sales was also zero due to steady decline in sales.
