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

Answer:

$f(4)=14$

Step-by-step 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 $14$
