Given the function $ g(x) = 2f(2x + 2) - 3 $ for the point $ (1, 2) $.
Now, we take 2 common and we get $ f(x) = 2f( 2(x + 1) ) - 3 $; the Horizontal stretch is $ \frac{1}{2} $.
Solving for x:
$2(2 - 1) = 2(1)$
Now, applying the stretch: $ \frac{1}{2} $. For y, the value is pretty simple: $ 1 $.
The answer, however, is $ \frac{-3}{2} $ for x.
What is the wrong step here?
Shouldn't it be independant of the step?
