The simplified answer is 17.48
Answer: D
<u>Step-by-step explanation:</u>
Vertex form is: f(x) = a(x - h)² + k where (h, k) is the vertex.
f(x) = (x - 3)² - 5
- the vertex is (3, 5).
- "a" is positive (+1), so it points upward.
The only graph that matches is the last one, <em>which I called graph D.</em>
Answer: It just means 100 - 77% which equals to 23%.
Decreased means reduced or basically taking away a percentage of something. In this case it's numbers in math.
Hope this helps!
