what is the range of f (x) = –2x + 1; {–2, 0, 2, 4, 6}

Sagot :

Answer:

[4,0,6,12]

Step-by-step explanation:

When x = -1, f(x) =  

2

x

2

=  

2

(

1

)

2

= -4.

When x =1, f(x) =  

2

x

2

=  

2

(

1

)

2

= 0.

When x =4, f(x) =  

2

x

2

=  

2

(

4

)

2

= 6.

When x =7, f(x) =  

2

x

2

=  

2

(

7

)

2

= 12.

So the values achieved, which is the range is  

{

4

,

0

,

6
