 1/30
Step-by-step explanation:
The zeros of the function are ...
-32 (multiplicity 2)5
So, the factorization for some leading coefficient 'a' is ...
 y = a(x +3)(x -2)²(x -5)
and the y-intercept is ...
 y = a(3)(-2)²(-5) = -60a
The graph shows the y-intercept is -2, so we must have ...
 -2 = -60a
 1/30 = a
The leading coefficient is 1/30.
