Q:

For each function f, find f^-1 and the domain and range of f and f^-1. f(x)=3x+4

Accepted Solution

A:
Answer:For x = 0 f ( 0 ) = [ ( 3 Γ— 0 ) βˆ’ 4 ] f ( 0 ) = [ 0 βˆ’ 4 ] f ( 0 ) = βˆ’ 4 For x = 1 f ( 1 ) = [ ( 3 Γ— 1 ) βˆ’ 4 ] f ( 1 ) = [ 1 βˆ’ 4 ] f ( 1 ) = βˆ’ 3 For x = 2 f ( 2 ) = [ ( 3 Γ— 2 ) βˆ’ 4 ] f ( 2 ) = [ 6 βˆ’ 4 ] f ( 2 ) = 2 For x = 3 f ( 3 ) = [ ( 3 Γ— 3 ) βˆ’ 4 ] f ( 3 ) = [ 9 βˆ’ 4 ] f ( 3 ) = 5 Therefore, the Range is: Β { βˆ’ 4 , βˆ’ 3 , 2 , 5 }explanation:To find the range, substitute each value of the domain into the formula and calculate the result [can i have brainliest?]
