Answer:
Step-by-step explanation:
Using the identity (a - b)^2 here ,
Answer:
a = 0
Step-by-step explanation:
3(4a+7)=5(2a+4)+1 Distribute 3 through the parentheses
- > 12a + 21 = 5(2a + 4) +1
5(2a + 4) +1 --> 10a + 20 + 1
12a + 21 = 10a + 20 + 1 --> 12a + 21 = 10a + 21 --> 12a = 10a
12a - 10a = 0 --> 2a = 0
Divide both sides of the equation by 2 --> a = 0

Substituting the data points into the model:
f(x)= -x2 + 2x -3
f(-2)=-11
f(0)=-3
f(1)=-2
f(3)=-6
f(5)=-18
So A is the right ans.
