The equation of the graphed function is;
f(x) = -3/[(x + 3)(x - 2)]
This means that at values of x = -3 or x = 2, the denominator becomes zero and the function becomes undefined.
(x + 3)(x - 2)
Thus, we have;
f(x) = a/((x + 3)(x - 2))
At (0, 0.5), we have;
0.5 = a/((0 + 3)(0 - 2))
0.5 = a/(-6)
Multiply both sides by -6 to get;
-3 = a
f(x) = -3/((x + 3)(x - 2))
