Answer:
D. Factor out 3 from the first two terms.
Step-by-step explanation:
Vertex form is ...
y = a(x -h)² +k
where (h, k) is the vertex and "a" is the vertical scale factor.
This equation expands to give ...
y = ax² -2ahx + ah² +k
Factoring "a" from the terms involving x makes it easy to identify h and so finish putting the equation into vertex form. In this equation, that means the most appropriate first step is ...
factor out 3 from the first two terms
First you add the 1/4 and 3/4 together forgetting the /4 and adding the 1+3, that makes 4/4 which is a 1 then add that 1 to the 1 and 2 left over to get the answer
The change is a growth of 2.5% so the factor will be:
1 + 0.025 = 1.025
N = 1000(1.025)⁶
= $1,160
