Question

f(x) = 6 x^5 + 4 x - 9

Answer 1

what is the question?

Answer 2

what is x

Answer 3

using the derivative

Answer 4

so what is x in 30x^4+4

Answer 5

x is a variable
there has to be something more specific that "what is x"

Answer 6

that's what im looking for the red my answer there is wrong

Answer 7

now we have a question!

Answer 8

\[f(x)=30x^4+4\] right?

Answer 9

i mean
\[f'(x)=30x^4+4\]

Answer 10

yes thats correct

Answer 11

that is what you are supposed to type in where it says
"the values of \(f'(x)...\)"

Answer 12

they are asking what \(f'(x)\) is equal to
they are not looking for a number
just type in \(30x^4+4\)

Answer 13

i did and it was incorrect. my classmates with a similiar problem had decimals which were correct

Answer 14

you typed in \(30x^4+4\) and it was incorrect?

Answer 15

yes i am looking for an exact answer

Answer 16

there is no "exact answer" it is just
\[f'(x)=30x^4+4\]

Answer 17

which is clearly always positive (that part you got right)

Answer 18

can i show you someone else's problem?

Answer 19

maybe the syntax was wrong, or there is a mistake in the systerm

sure

Answer 21

which had a correct answer

Answer 22

just kidding their answer was wrong but look

Answer 23

yeah of course it is wrong

Answer 24

the derivative is not \(40x^2+4\) it is \(30x^4+4\)

Answer 25

oh yes i am so sorry. you are correct

Answer 26

i put the derivative and it was correct
thank you

Answer 27

whew you had me scared for a moment
