Answer:The function v(x) has the largest value when x = 4.
Solution:
x=4;
e(4) = 4^2 + 6×4 + 21=16+24+21=61
m(4) = 8×4=32
v(4) = 31×4=124
v(4)>e(4)>m(4)
Therefore,The function v(x) has the largest value when x = 4.

Step-by-step explanation:
<span>Let z be the percent of the cup that is oats.
Therefore 310*z + 290 * (1-z) = 302.
310z-290z+290=302.
20z=12
z=12/20 = .6.
Therefore the new cereal is 60% oats and 40% wheat flakes.
A cup of the cereal then contains 3/5 cup of oats, and 2/5 cup of wheat flakes.</span>
