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.

Respuesta :

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.
