Step 1
In this question we have
Zeroes -6 and 5
which goes to

- \infty a s x \to - \infty

Step 2
For finding the polynomial function we need zeroes
Zeroes are -6 and 5
so,

x = - 6 and x = 5

x + 6 = 0 and x - 5 = 0

So, the polynomial is

y = (x + 6) (x - 5)

y = x (x - 5) + 6 (x - 5)

y = x^{2} - 5 x + 6 x - 30

y = x^{2} + x - 30

Step 3
Given condition is

y = - \infty a s x \to - \infty

So, we need the coefficient of

x^{2}

negative
So,

y = - (x^{2} + x - 30)

Answer:

y = - x^{2} - x + 30
