Answer: q(x) = 0.005(x - 40)² + 70
<u>Step-by-step explanation:</u>
f(x) = a(x - h)² + k <em>where a is the vertical stretch and (h, k) is the vertex.</em>
Which coordinate shifts the graph up?<em> The y-coordinate for the vertex is k.</em>
p(x) = 0.005(x - 40)² + 60
q(x) = 0.005(x - 40)² + 60 <u>+ 10</u>
= 0.005(x - 40)² + 70
Answer: D. History
Step-by-step explanation:
To answer this question, we need to use the z-score formula written below:

Now we'll just plug in the numbers and solve.
History:

Biology:

As we can see, history wields a higher z-score than biology, thus leaving us with option D. History
