Question

If f(x)=3x+5 and g(x)=x-1,then f[g(0)]

Answer 1

F(g(x)) = 3(x-1)+ 5
F(g(0)) = 3(0-1)+5
= -3+5
= 2

Answer 2

The answer is:  " 2" . 
___________________________________________
Answer:  " f[g(0)] = 2 " .

Explanation:
___________________________________________
Given:  " f(x) = 3x + 5" ;  and:  " g(x) =x − 1" ;   

Question to solve:  "What is:  f[g(0)]  ? "   ;
__________________________________________
What is "ef" of "gee" of "zero"? 
__________________________________________
Let us begin by finding "g(0)" ;

Given:  " g(x) = x − 1 " ;

To find:  " g(0) " ;  we plug in "0" for all values of "x" ; and solve; as follows:

→  " g(0) = 0 − 1 = -1 " ;

→ So;  " g(0) = -1 " .
_______________________________________________________
We are asked to find:  " f[g(0)] " ;  

which is:  " f(-1) " .

Given:  "f(x) = 3x + 5"  ;   

→  To find " f(-1)" ;  we plug in:  "-1" for all values of "x" ;  and solve; as follows:

→  " f(-1) = 3(-1)  + 5  =  -3 + 5 = 2 .
