$y = 4^x \quad \to\quad y = - \frac 2 3 (4^(x+7)) - 5$

y=4^x

OK, we'll go in steps. First a reflection through the x axis, which negates y.

y = -4^x

Now a vertical scaling of 2/3

$y = -\frac 2 3 \cdot 4^x$

Now we shift seven units to the right,

$y = -\frac 2 3 \cdot 4^(x+7)$

Now down five,

$y = -\frac 2 3 \cdot 4^(x+7) - 5$

There it is.

Answer: reflection thru x axis, vertical scale 2/3, right shift 7, down 5, second choice
