Step-by-step explanation:
h(-1) simply means that x=-1, and we use that everywhere in the function, where x appears, and simply calculate the result.
that is how a function works. out of an input value (x) we generate/calculate a result value (y).
(2x - 6) / (4x² + 8)
x = -1
(2×-1 - 6) / (4×-1² + 8) = (-2 - 6) / (4×1 + 8) = -8 / (4+8) =
= -8/12 = -2/3
h(-1) = -2/3
