the answer I knew but I forgot at ate
The given equation is

It is given that , when x=0, f(x)=36
Substituting these values

So the missing value of a is 2 .
Answer:
c.
Step-by-step explanation:
The equation can be written in vertex form as
y = a(x +2)² - 3
Substituting the given values, we can find the coefficient "a".
-5 = a(-1+2)² -3
-2 = a . . . . . . . . . add 3 and simplify
The coefficient of the squared term is -2.
