Question

What is f left parenthesis 4 right parenthesisf(4) for the function f left parenthesis x right parenthesis equals 2 x plus 6f(x)=2x+6​?

Answer 1

`f(4)=14`

Explanation:

Given function is
`f(x)=2x+6`

We need to find the value of
`f(4)`

For any function
`f(x)` if we want to find the value of
`f(a)`, we need to plug
`x=a` in the function.

So, we will plug
`x=4` in the function
`f(x)=2x+6`

`f(4)=2(4)+6\\f(4)=8+6\\f(4)=14`

So, the value of
`f(4)` in the function
`f(x)=2x+6` is
`14`
