Question

Let ​f(x)= -5x+6. Find and simplify ​f(3n−5​).

f(3n-5)= ?

Answer 1

We know that our function is
`f(x)=-5x+6`; the only thing we need to find
`f(3n-5)` is replace
`x` with
`(3n-5)` in our original function:

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

`f(3n-5)=-5(3n-5)+6`

Now, lets simplify our function:

`f(3n-5)=-15n+25+6`

`f(3n-5)=-15n+31`

After simplify our function, we can conclude that
`f(3n-5)=-15n+31`
