IM TAKIN A CALCULUS FOR BUSINESS COURSE AND I NEED TO SOLVE THIS PROBLEM..

Use the four step process to find f(x) and then find f(1),f(2),f(3)

f(x)=2-3x3. (that x at the end is cubed)...

and the answer for f(x)=-6x. thats the first answer, i just need to know howd they get that answer. procedures!!

i haven't started calculus yet, but i would guess that you would just substitute.

f(X)=2-3(1)^3

f(X)=2-3^3

f(X)=2-9

f(X)=-6

but i dunno, as i said, i'm not in calculus till november.

f(X)=2-3(1)^3

f(X)=2-3^3

f(X)=2-9

f(X)=-6

but i dunno, as i said, i'm not in calculus till november.

For the record, x cubed=x^3

I'm pretty sure your calculus teacher doesn't know ****, or you wrote the problem wrong. In no way is f(x) -6x if f(x)=2-3x^3. Even if your trying to find the derivative, which I think you are, that's still not right. Are you sure you know what the problem is asking?

...this isn't calculus ? I'm in AP calculus BC and this just seems like an algebra 2 substitution problem...

oh, well when were you in arithmetic?

what allan143 said is irrelevant.

Yeah that's pretty ****ed. Definitely a business related calc problem. Try this.

f(x)=2-3x3. (that x at the end is cubed)...

derivative=

0-3*x3

=-3*3x2

=-9x2

f1(x)=-9x2

i think. If that is what your trying to find.

derivative=

0-3*x3

=-3*3x2

=-9x2

f1(x)=-9x2

i think. If that is what your trying to find.

Damn you got it wrong! Potence is not transitive!

in your case that would be

f(x)= 2-3.x^3

f(x)= 2-3.(1^3)

f(x)= 2-3 = -1

But anyways I think the TS has to explain himself better.

Hey TS try rewriting your question, but post it in this thread (Math/Science Help Thread): https://www.ultimate-guitar.com/forum/showthread.php?p=21553704#post21553704
