-$$f ( x ) = x ^ { 2 } + 5 x - 4$$
A) $( 0 , - 4 )$
B) $( 0,1 )$
C) $( 0,4 )$
D) $( 0,5 )$

The y-intercept of a function is found by setting $x = 0$ and solving for $y$. For the given function $f(x) = x^2 + 5x - 4$, when $x = 0$, $f(0) = 0^2 + 5(0) - 4 = -4$. Therefore, the y-intercept is $(0, -4)$.
