To find the y-intercept of a function $f(x)$, follow these steps:

1. Set $x = 0$ in the given function $f(x)$.
2. Compute $f(0)$, which is the value of the function when $x = 0$.

For example, if the function is:

$f(x) = ax^2 + bx + c$

then substituting $x = 0$:

$f(0) = a(0)^2 + b(0) + c = c$

The y-intercept is $(0, f(0))$.

If you provide the specific function $f(x)$, I can compute the y-intercept for you.
