Question 23
Let f be a function given by f(x)=-4x-1.
Find and simplify f(x+3)

f=-

Step-by-step explanation:

Divide each term in  f ( x+ 3 ) = − 4 x − 1  by  x + 3  and simplify.

28/24 = 1 4/24  or 1 1/6

to simplify the answer you divide the denominator into the numerator and get 1 4/24

then reduce 4/24 by dividing the greatest common multiple into the numerator and the denominator to reduce the fraction to the lowest terms  so 4/24 = 1/6   when it is divided by 4   

So that gives us the final answer of  1 1/6
