8. Q8(a) Determine the coordinates of the vertex A of the parabola \( f(x) \). Type a response Another parabola is described by the function \( h(x)=(x-a)(x-b) \), where a and b are roots of the function. The \( y \)-coordinate of the vertex of the parabola \( h(x) \) is - - and it also passes through point \( A \). Q8(b) Since \( h(x) \) passes through point \( A \) and the y-coordinate of the vertex is -4, find the function \( h(x) \) in standard form.

Quick Answer
### Q8(a)
Without the function \( f(x) \), the coordinates of vertex \( A \) cannot be determined.
### Q8(b)
The function \( h(x) \) in standard form is \( h(x) = x^2 - (2a + 4)x + (a^2 + 4a) \).
