Looks like calculus not pre-calculus to me by the way. I do not see how to do it without taking the derivative.

**Pre-Calculus/Calculus**

I am too embarassed to ask this Calculus (really pre-calculus) question in tutoring, because I know I should know. Is the inverse of f(x)=3x-1 actually f(x)=1/3x+1? How do I find it? What if it asks the same equation replaced with f to the -1 power (x)? I think I know how the ...

You need to write out the question. I have no idea what "pre calculus" this could be, maybe zeroes, however, that is standard fare for an algebra course.

I am in Honors Pre-Calculus and am having a hard time understanding my teacher. I feel so stupid. Does anyone have any suggestions on a website that might give me some insight into what I am doing wrong? Thanks!

**pre calculus**

Pre-Calculus? I wonder what the question is. In a basic algebra course, you would be looking for zeroes, and probably get those by factoring. 2x^2+11x-21=0 (2x-3)(x+7)=0 x= 1.5, or x=-7

**math**

Are you doing pre-calculus or calculus? In calculus, the maximum is obtained by setting f'(t)=derivative with respect to t = 0 and solving for t. In pre-calculus, you can transform the expression by completing the squares. Ax² + Bx + C =A(x²+ (B/A)x + C/A) =A((x + (B...

**Pre-Calculus**

Pre-Calculus? That is a nasty equation. We might use Newton's Method, but that would be Calculus. I tried some "trial and erro" and got x = appr .371 using 2 decimals 4 sin .37 = 1.44646 e^.37 = 1.4477 I am curious what method was suggested that you should use.

**Math: Pre-calculus**

P=2(W+L) A=WL, so L = 180/W so, P = 2(W+180/W) This is pre-cal, so you don't have calculus at your disposal. But, you do know that a square has maximum area for a given perimeter. So, W = L = √180 = 6√5

**Pre-calc**

Pre calculus? This is stock Algebra II. put the equations in the form of ax^2+bx+c=0 then factor. for instance, c is already in that form. 2x^2+x-6=0 (2x-3)(x+2)=0 x= 3/2 x=-2 do the others the same method.

**Pre-Calculus**

well, shoot. Then just subtract 8 from both sides to get 3x^2 = -12 x^2 = -4 there is no real solution, since x^2 is never negative for real x. If you allow complex solutions, then x = 2i or -2i. I believe this is from Algebra I, and should not be posing a difficulty for ...

In Kentucky, where i am from, we do algebra and algebra two before pre-cal and calculus. I didnt realize that the problem could be solved in multiple ways and i apologise. But the solution should be done without calculus.

**Pre-Calculus**

The "dx" at the end makes me think you are supposed to integrate [e^-x / e^-1] + 3 . But that would make it a calculus, not a precalculus, question. It is not clear what the question is. In any case, e^-x / e^-1 = e^(1-x) The integral of e^(1-x) + 3 dx is -e^(1-x) + 3x + C
