Answer:it would be 7/12 I think
Step-by-step explanation:
Answer:
0.75
Step-by-step explanation:
The given sequence is an AP , as the difference of all the terms is same

Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20
