Question

Evaluate f(3) for the follow f(x)=x-5 f(3) =​

Answer 1

f(3) = - 2

Explanation:

To evaluate f(3), substitute x = 3 into f(x) , that is

f(3) = 3 - 5 = - 2

Answer 2

If
`f(x)=x-5`, f(3) = -2

Explanation:

We are given
`f(x)=x-5` and we need to find f(3)

For finding f(3), we put x= 3 in the given function.

`f(x)=x-5`

Putting x=3

`f(3)=3-5\\f(3)=-2`

So, if
`f(x)=x-5`, f(3) = -2
