Which of the following functions has the largest value when x = 4? e(x) = x2 + 6x + 21 m(x) = 8x v(x) = 31x e(x) v(x) m(x) all the functions are equal at x = 4.

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.
