Question

If ​f(x)equalsxsquaredminus6xplus5​, it is possible to find ​f(xplus4​) by replacing each occurence of​ _______ by​ _______.

Answer 1

It is possible to find ​f(x+4) by replacing each occurrence of​ x by (x+4).

`f(x+4) = x^2 +2x -3`

Explanation:

We are given the following function in the question:

`f(x) = x^2-6x+5`

We have to find the value of f(x+4).

It is possible to find ​f(x+4) by replacing each occurrence of​ x by (x+4).

This can be done in the following manner:

`f(x) = x^2-6x+5\\f(x+4) =(x+4)^2 - 6(x+4) + 5\\f(x+4) = x^2 + 16 + 8x - 6x - 24 +5\\f(x+4) = x^2 +2x -3`
