What is the inverse one to one function of f(x) = square root of x-2???

Answers

Answer 1

Answer: $f(x) = √(x - 2) \ny = √(x - 2) \ny^(2) = (√(x - 2))^(2) \ny^(2) = x - 2 \nx^(2) = y - 2 \nx^(2) + 2 = y \nx^(2) + 2 = f^(-1)(x)$

Which expression gives the number in the nth position in the sequence?
A) 2n - 2
B) 3n + 4
C) 4n - 1
D) 5n

Answers

Answer:

Option B is correct

3n+4[/tex]

Step-by-step explanation:

The nth term for the arithmetic sequence is given by:

$a_n = a_1 +(n-1)d$ ....[1]

where,

$a_n$ is the nth position

n is the number of term

$a_1$ is the first term and

d is the common difference.

Given the table:

Position(n) Value of Term( $a_n$ )

1 7

2 10

3 13

4 16

5 19

6 22

from the given table:

At n = 1 ,

$a_1 = 7$

At n = 2

$a_2 = 10$

at n = 3

$a_3 = 13$ and so on

Common difference(d) for the sequence is 3

Since,

$d = a_2-a_1=a_3-a_2.....$

⇒ $d = 10-7=13-10......... = 3$

Substitute d = 3 and $a_1 = 7$ in [1] we have;

$a_n = 7+(n-1)(3)$

⇒ $a_n = 7+3n-3$

⇒ $a_n =3n+4$

Therefore, the expression gives the number in the nth position in the sequence is, $3n+4$

3n+4
3(3)+4
9+4
13
is the B).

Answer:

second option is correct (for question no 20)

Step-by-step explanation:

coordinate points are:

(3,1) = (x1,y1)

(5,9) = (x2,y2)

slope (m) = y2-y1/x2-x1

=9-1/5-3

=8/2

Now using slope intercept form

y=mx + b

y=4x + b

since the line passes through the point (3,1) it satisfies the equation

y=4x + b

1=4*3 + b

1-12 = b

-11 = b

substituting the value of b in equation

y=4x + b

y=4x +(-11)

y=4x - 11

Find f[g(5)]

A. 92
B. 2
C. 30
D. 242

Answers

Answer:

Step-by-step explanation:

Evaluate g(5), then use the value obtained to evaluate f(x) , that is

g(5) = 2(5)² - 4(5) = 2(25) - 20 = 50 - 20 = 30, then

f(30) = 3(30) + 2 = 90 + 2 = 92
