The y-intercept is the value of $y$ $y$ at the point on the function where $x = 0$ $x=0$

$y = {(\frac{1}{2})}^{x} - 4$ $y=(1/2)^x-4$ with $x = 0$ $x=0$

$y = 1 - 4 = - 3$ $y=1 -4 = -3$

The y-intercept is at $(- 3)$ $(-3)$

Set $x = 0$ $x=0$ in your function and remember that $a^{0} = 1$ $a^0=1$ .
