Divide both sides by 72:

Answer:
The vertex of this equation is (2, -7)
Step-by-step explanation:
In order to find the vertex of this equation we start with the base form of the vertex form.
y = a(x - h) + k
With this equation (h, k) is the vertex. You can see that 2 lines up with h and -7 lines up with k. This shows that (2, -7) is the vertex.
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.
