Question

If f(x) = 2x - 3, find the following:
A: f(-2)
B: f(7)
C: f(-4)

Answer 1

Answer:

here it will be - 7 , 11 , - 11  

Step-by-step explanation:

given there F ( X ) = 2 X - 3

         HERE F ( - 2 )   =  2 ( - 2 ) - 3    

HERE   F ( - 2 ) =  - 4 - 3

HERE F ( - 2 )   = - 7

HERE  F ( 7 ) =  2 ( 7 ) - 3

  HERE F ( 7 ) = 14 - 3

HERE F ( 7 ) = 11

HERE F ( - 4 ) = 2 ( - 4 ) -    3

HERE F ( - 4 ) = - 8 - 3

HERE F ( - 4 ) = - 11

Answer 2

A. f(-2)=2(-2)-3

f(-2)= -4-3

f(-2)= -7

B. f(7)=2(7)-3

f(7)=14-3

f(7)= 11

C. f(-4)= 2(-4)-3

f(-4)= -8-3

f(-4)= -11
