Question

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.

Answer 1

c?

Answer 2

@triciaal

Answer 3

the only exponent is \(x^2\) right?

Answer 4

yes :)

Answer 5

8x is 8^x also 31x is 31(x)

Answer 6

\(x^2\\8^x\\31x\)
like that?

Answer 7

plug 4 in each of the functions and see which is the largest value

Answer 8

yes

Answer 9

i did i got c but I'm making sure

Answer 10

i'm asking if it's like this
\(x^2\\8^x\\31x\)

Answer 11

yes it is @Mehek14 i already said that :)

Answer 12

if this is what u mean
e(x) = x^2 + 6x + 21
m(x) = 8^x
v(x) = 31x
then when we plug in 4 we get

e(x)= 61
m(x)= 4096
v(x)= 124

Answer 13

meaning m(x) is the highest value

Answer 14

C is correct

Answer 15

ok i thought so thank you everybody ! :)

Answer 16

you're welcome :D

Answer 17

yes C
