Question

Find f(x-4) if f(x)=7x+1

Answer 1

first lets substitute (x- 4) in place of x in function

f(x-4) = 7 (x-4)+1

Now let's simplify the expression

f (x-4) =7x -28+1

= 7x -27

Answer 2

the function f(x-4) is equal to 7x - 27.

Explanation:

To find f(x-4) when f(x) = 7x+1, you simply replace x in the function with (x-4).

So, you have:

f(x-4) = 7(x-4) + 1

Now, you can simplify this expression:

f(x-4) = 7x - 28 + 1

Combine like terms:

f(x-4) = 7x - 27

So, the function f(x-4) is equal to 7x - 27.
