Which of the following functions has the largest value when x = 3? (1 point)

c(x) = 3x2 + 5x + 22
j(x) = 12x
a(x) = 9x

all the functions are equal at x = 3.
c(x)
j(x)
a(x)

X = 3

c(x) = 3x² + 5x + 22 
⇒ c(3) = 3(3²) + 5(3) + 22 
⇒ c(3) = 3(9) + 15 + 22
⇒ c(3) = 27 + 15 + 22
⇒ c(3) = 64

j(x) = 12x
⇒ j(3) = 12(3)
⇒ j(3) = 36

a(x) = 9x
⇒ a(3) = 9(3)
⇒ a(3) = 27

c(x) = 3x² + 5x + 22 is the function that has the largest value when x = 3.

False. Not all functions are equal at x = 3.
