If x is an even number, the function f(x) = 2x − 1 gives an odd number. identify the set of odd numbers corresponding to this set of even numbers: {0, 2, 4, 6, 8}. a. {3, 5, 7, 9, 11} b. {-1, 3, 7, 11, 15} c. {1, 3, 5, 9, 11} d. {5, 7, 9, 11, 13}

B. {-1, 3, 7, 11, 15}

Step-by-step explanation:

The given function is

To find the corresponding odd numbers, we substitute the even numbers as x-values into the function.

When x=0,  

When x=2,  

When x=4,  

When x=6,  

When x=8,  

Therefore the set of odd numbers corresponding to this set of even numbers are  {-1, 3, 7, 11, 15}

B. {-1, 3, 7, 11, 15}

Step-by-step explanation:

In order to find the set of corresponding odd numbers then we have to put the even numbers one by one as we already know that x can only have even values..

So,

Putting x = 0

2(0) - 1

=0-1

= -1

Putting x=2

2(2) - 1

=4-1

=3

Putting x=4

2(4)-1

=8-1

=7

Putting x= 6

2(6) -1

=12-1

=11

Putting x=8

2(8)-1

=16-1

=15

So the corresponding set for  {0, 2, 4, 6, 8} is {-1, 3, 7, 11, 15}

Hence, option B is the correct answer ..

the answer is d.x= 90°

y= 50°

arc lm= 100°
