$f (2) = 34$ $f(2)=34$

We don't have an explicit expression for $f (x)$ $f(x)$ but we can directly calculate a linear transformation of $f (x)$ $f(x)$ .

We have:

$f (2 x - 4) = 8 x + 10$ $f(2x-4)=8x+10$

So let us find the value of $x$ $x$ st $2 x - 4$ $2x-4$ equals $2$ $2$

$2 x - 4 = 2 \Rightarrow 2 x = 6$ $2x-4=2 => 2x=6$
$:. x=3$

So let us substitute $x=3$ , which gives us:

$f(2(3)-4)=8(3)+10$

$:. f(2)=24+10$
$:. f(2)=34$
